When I was going for small and inexpensive, I was looking at stuff on sound professionals. You can get the CMC-4 mics (SP modded AT 853's I believe) and a SP-SPSB-1 batt box. You may or may not want to get the preamp in it (I don't know anything about DAT decks). It's a $140 option, but all of that would still come in under your budget.
