Gregg,
I've gotten a bunch for the $150-$250 range, but I called the same places in NC I'd purchased them before for some forum memebrs and couldn't find any under $450. Granted, I bought my first one in 2000, but it seems as time has gone on the $200 tranny is hard to find.
I also bought a new one from GTA for $1200 back before anyone on the forum had done anything with GTA . I don't think they are that cheap anymore, but you could ask.
