I'm afriad you're wrong, you can't get them brand new anywhere anymore. I did find a website not so long ago advertising them (can't remember the price now) and apparently they had 2 left in stock. I sent them an email immediately showing interest in aquiring at least one of the cards, but recieved no reply. Following that I sent two more emails but again no reply. To be honest I'd be suprised if they'd really been on offer as brand new anyway - all the cards were surely snapped up a long time ago, or went West after DCE went bust.
I think £350 is quite a lot of money to pay, you're right, but we're talking about the highest speccd accelerator card available for the Amiga at the moment, and they are extremely rare in that anyone who has one wants to keep it, you rarely see them for sale. Bidding was tough on that item, there were a few people interested and willing to pay a lot of money for it - I think that's a good thing we can be positive about. I mean, the Amiga market is obviously STILL bouyont enough that people are willing to spend money on their machines.
As for me, that accelerator pretty much finishes off my main A1200 - there aren't many ways you can improve on my setup anymore! Not until (if/when) Elbox release their range of SharkPPC cards anyway.
