Hey Yo!
Although the A3000 is a lovely machine, i would pick the A4000 over the A3000, simply because of AGA thugh. Even though AGA vastly underachieved, it is still worth it for the limited good games and demos available. Also some compatibility with software as well that only use native chipset. Man, i wish they commercially released the A3000+, that is the holy grail! :-D
