if that makes any sense...
Basically, I want to run cables from my mics in the air as balanced down to my unbalanced recorder. I figure if I "unbalance" them near the recorder, I will maintain basically all of the benefits of balancing as the long run of cable will be balanced. Would an adapter like this: http://www.bhphotovideo.com/c/product/431406-REG/Hosa_Technology_MIT_435_MIT_435_Female_XLR.html maintain the balancing from the mics to the adapter? I know the 1/4" is unbalanced, but will the mic to xlr on the adapter still be balanced? Is this the right type of adapter? If not, does one exist?

The adapter will do the job.
But it will modify the sound and probably not for better. Small, low-price are not things that suggest good sound in transformers.
My suggestion is that you get a preamp instead.

I've supplied many with a DIRECT WIRED (NO TRANSFORMER) dual XLR Balanced Jack-to-3.5mm miniStereo R/A plug connected directly into the deck.  Using this you would run your balanced extension cables down from your stand, then connect to the patch adapter near deck.  I see no issues if not running over power cords on way to patch adapter.  This and other patch cords on my site at http://www.sonicstudios.com/access.htm#adapters.

That's a step-up transformer, you don't want that.  A regular ol' 600:600 will do, or a 500:10K would be OK if your mics are low impedance.  But that thing is 200:50K, that ratio is far too high for what you want to do.

Also, you need to consider how you are powering the mics; that would work with dynamic mics, otherwise you need a power supply between the mics and the transformer.
These take a AA battery and are self powered so no worries there. Where could I get a tranformer like that?
