Thanks for your replies guys.
One of the reasons I asked about the A2000 is that I saw one going on ebay (green screen :-) ), 3GBP no reserve..., and picked it up for 10.50GBP in the end (which I s'pose is about 15USD). I always wanted one of these when I was a kid, and now I have one!
I wouldn't be an Amiga fan if I worried about things being outdated. You wouldn't ask someone who works on and drives his classic Jaguar E-type why he hasn't sold it and bought a newer car would you!
Anyway, I've been doing a bit of reading on the 'net about the wildfire card, and yes, I WANT ONE! But the chances of finding one and not having to pay through the nose are so low.... As I was saying before, even if I did find one on ebay for example, these people always seem to come from nowhere and bid stupid amounts of money. I saw someone buy the Blizzard 1260 on ebay the other day for 200GBP! I'm sure you can still get a new one cheaper from Vesalia!
