got my current rig from sweetwater sound's trading post...i called it the taper starter package...got a d8, stock sbm1, rmr-3d and at822 stereo mic and a huge pelican case for under $600. I used this package for about a year....
i have since bought some new 391 mic off ebay
i am assembling all the things i need to run those mics now: the phantom power, line converters, good shock mounts(8410's) and a shure verticle stereo bar. all these items i have gotten used from people on this taperssection board, or the oade used gear board, or the dat heads list.
i have found that tapers are very friendly, and have a certain integrity to them above the average ebay transaction, possibly because we all know this ain't a cheap hobby
good luck on your quest....you may want to sell/trade some of your studio gear for the portable gear, that's what I did...sold a fostex model 80 analog 8 track 1/4" real-to-real deck, and adat xt(have 2 more though) to feed this habit
