So if I was going to get a second amiga, which?

Your second AMIGA?
A3000: you don't need to change the caps.
A4000: you must change the caps.

I'm curious about that (since I have an A1000, A500, A2000 and A1200).

Which Amiga models require cap changes? Why is that (were sub-standard caps used in A1200s/A4000s?)? When do they fail? Any tips on increasing longevity?

Thanks!
