You should consider the fact that you are going to be spending a lot of money.
Graphics cards and accelerator cards are hard to find and expensive, unfortunately. That is, unless you are lucky and find one in a boot sale. Otherwise on Ebay they go for high prices.
Maybe in the U.K. it is different - I think Amigas held on a little longer there.
Here in Canada though, you're only likely to find one even at a flea market or in the local classified ads once in a very blue moon.
Good luck though!
