I've upgraded and had no issues, but in fairness, I had no issues (running into the R-44, at least) before.

Same here.

Would the Tekkeon MP3750 work fine with a SD USBPre 2 and a Tascam DR680?

The 3450i would be better

agreed

I've used my 3450i to power the pre2 before.

Also I'd be very careful powering the 680 off a Tekkeon. If you do, be sure to use the manual 12v setting.  Even then, I'd be awfully cautious.

Also, my third (!) 680 STILL will not take a feed from a USBpre2, even with the SD box's firmware updated.

Just curious but what would make a 3450i better choice?

The 3450i gives more DC output options.  The 3750 is limited to 10v and 19v only.  Kinda odd for taping purposes.

Oh, okay, then I can understand the benefits over the 3450. Since the 3750 is a higher model number, I figured it would be better. ;)

plus the industrial model has more Wh. 58 compared to 50 IIRC.

I remember the operating temperature tolerances are higher on the i models.

Apparently the 3450i R2 has the USB port.

Yes. Sorry for the misunderstanding, the i=R2 models do, the i-R1 don't.

The good news is that they have been making the R2 units for a good 6+ months so it shouldn't be really hard to find one. I had to hunt when I first got mine.

Weird. Did sound devices offer any solutions?

not yet. still thinking. They are debating having me send it to them for tests.

Update:
sent it in, they found issues, they are sending me a replacement.

I now have machines with different versions (previously they were both 10.5.8), one is still on .5 the other is up to .6 now. The small dropouts are still found with the new unit on 10.5.8, but are absent on the 10.6 machine. SD verified other issues with the box so the swap wasn't in vein, but this does pose an interesting question about what changed in OSX between 10.5 and 10.6 that caused the USB audio to improve.

I'm curious, you say small dropouts and you listed VLC as the playback software, any chance that the interaction between VLC and new OSX could be the root of the issue? Maybe VLC had the weird dropout and it's not  related to your mac system at all? 

Then off topic, how come you chose VLC.  I do like that program and in fact talked the college where I work into installing it on all classroom computers since it will play ANY video no matter how old it is. Bottom line is I got tired of getting called to classrooms to figure out why some old ass piece of software an instuctor was using wouldn't work.  We'd just intsall VLC and poof everything is fine but since the school uses imaged drives the instal goes away at shutdown.  I digress, but I never thought to use it as an audio playback and wondered why you ended up using it.....

OK sorry for hijack.........back to USBPRe2..... 
I have been using mine with the 15dB pads on all the time now after having some issues with clipping onstage mics with really loud bands.  anyone else notice the clipping issue?
