i would second the comments about asking dusty directly about the old aa gear. that said, i would still grab a modded art di/o for <$200 & never look back. all the other suggestions are good ones - but not for <$200.
if yure wanting to spend <$1k, then the other options are good - scott nixon, benchmark, ack!, etc... and a modded di/o would still be in the game. now, system synergy & personal taste will come into play. but, if ya wanna spend <$200, yust get the modded di/o & forget about it...
ymmv,
