yea, i'm workin with MD now, but i'm workin on laptop my laptop rig... i know thats hard for stealtyness, but i always got my MD. I have some good sounding shows, and some bad ones.. i've had only bad results from mini-mics... i've heard some pretty damn good quality shows with AT851's, but yea.. depends on what your gonna do, if your gonna stealth shows, and they are gonna be picky about searching you, then stay as small as possible, but some shows i stealth at, i bring one AKG391 and run mono, and you don't get the compression of LP2 or LP4 running mono.. it still encodes at 44.1, but i'd recomend gettin good mics.. and run MD for now, look into upgrading in the future if you dig it.
peace.
