Before doing this ask yourself what you would like to do with it.
If you just want it for games then an old A500 might suffice or a cheap plain and standard A1200.
If you want to do some serious gaming then you might want a A1200 with an expansion card like a Blizzard1230 for those games that run a little slowly on unexpanded boxes.
If however you're thinking of getting one for OS4... then you're bonkers :-D but that's probably incurable, so I'd say A1200+BPPC+BVision or an A4000+CSPPC.
Obviously I started that list at the least expensive and worked up!
