I've just come back from the first part of a Grays auction for the liquidation of Optima computers - I only bought some office furniture.
The second part of the auction for the actual computers is now on.
Interestingly, there is a lot of Canon and Nikon camera stuff up for auction and some
Meade items (prisms?) as well.
Might be worth a look if you're in the market for a cheap laptop or camera accessory.
Auction is
here.
