Yeap!
I think your best choice is to buy an A4000.
I was working for years with my A4000T with OS3.9 with Boing Bang 2 with no problems at all. Of course you need kickstart rom 3.1. The only bad thing about A4000T (as mentioned from mr.cass) is the size of the tower! Is too huge for a normal desktop...
Anyway, first of all, I was changed a lot of A's, 500, 500+, 1200, 3000, but the A4000T is my last love from A's serries!
Take a fun!
:-P :-P :-P
