C460s are phantom-powered XLR out mics. I would also go for an all-in-one. You don't have time to get a tinybox before Feb. 8, so that will probably further influence your decision.
The tinybox/M10 crowd is usually interested in flexibility, so they aren't necessarily always running the tinybox--they might run mini-mics direct or with a battery box on other occasions. And almost half of tinyboxes are sold to support "active" capsule configurations, where the mic body isn't used and phantom power is thus not required. The advantage there is smaller footprint up on the stand and much lower power consumption which yields very long runtime. An active tinybox-M10 setup could run all day.
The C460s are very efficient mics though, so your runtime will be as good as it gets for a recorder with phantom.
Jon - thanks for your input and more technical information. Learning the C460s were phontom-powered is what I think was pushing my thoughts more towards an all-in-one and it just kind of seemed just kind of seemed if I could get one with xlr jacks it would avoid the need for additional adapters or trying to figure that all out. With an all-in-one I thought I could eliminate some of the initial learning curve by plugging mics directly into the deck and worry more with learning deck settings while picking up more knowledge as time goes on. There's just SO much to learn! haha
I mulled over the bigger all-in-one decks until 4 this morning and then spent most of today trying to decide. I really liked the Roland R-26 from the reviews I've read etc, but then the more I thought about the sticker price dipping into some of the expense of the other items I'm going to initial need, ie, clamps, stand, bag etc, I settled for now on the DR-40. It was nearly $15 cheaper yet this afternoon went I checked online so I ordered it through Amazon for a mere $124 shipped. Figure if nothing else, I'll buy a little of time to learn more and to learn more about some of the bigger decks before spending $400 or $500. From what I've read the DR-40 will probably serve my purpose for now and if it doesn't, I'm not out a lot of money and I can learn a little bit about settings in the mean time.
Of course, now I've got Jon also saying to get an all-in-one recorder, and I'm thinking of recanting.
I didn't realize the Neumann supply you got with that ebay auction was a battery supply, I thought it was AC. If you already have a battery operated phantom supply, getting a used Sony M10 might make some sense. They have good built-in gain (preamp) and are low noise. Pick up a used one for $200 or under, and use it with your Neumann supply and AKG mics.
If you want to upgrade later, given how easy it is to resell used M10's, you can then sell the M10 and the Neumann supply. Then you can get going with taping for only another $200, and the M10 is quite acceptable. Decide afterwards what you want from sound, amount of money into the hobby, tradeoffs of size vs flexibility vs sound vs cost, etc.
I'm sure you could resell the M10 for $175 or so, so you'd only be out $25 for the first round rig should you decide to upgrade.
Todd - I almost went this route. With the excellent reviews and popularity of the M10 it was very difficult not to do so especially when B&H has them marked down to $199 right now for red or black. I was just worried about rushing to figure out adapters or what have you to connect the mic xlr's etc and sort of got frustrated and went with what I "think" I know should hook right up with the DR-40. I may still in the very near term go with an M10, in fact I still haven't completely given up on the notion of just ordering one now and seeing which I can learn easier etc. As you say, given the M10 resale potential it wouldn't be much of a loss if any at all.
I'll be behind you to your right running CA-11 > CA 9200 > M10.
Great to know someone else will be there taping, maybe we could meet up prior to the show. I pm'd you.
I would say go with a cheaper all in one as well. That's all you need for now and can add a preamp later on if so desired
Thanks, your advice has definitely helped ease my mind a little since this it what I ended up doing after second guessing my decision all weekend.
I too am thinking with the DR-40 if nothing I can get in the game and learn. Aside from the mic setup, it's minimal cost and if it doesn't work out or once I get comfortable understanding operating a deck, then I can figure out which to grow into.
