I'd get the Matrix because of it's great speed and accuracy, but it will definately cost more than $400 (if you find one for that much or less, let me know and I'll buy one too). Bushy's aren't all bad, you'll need a new barrel for it, and the trigger is sloppy, but you get alot for $450 (14bps, PDS, what more could you want?). Between that and the impy I'd call it a tossup, either or. The cocker will have a lower ROF (unless you get an Eblade, but the kit alone costs $350, so that's unlikely), and they're very intricate, so do your homework before buying one. Those are all very good markers, and the best thing to do would be to try all of them and see which one best suits you. Good luck.
