you,ll need a remorgage when you see what those guys have for sale
Actually, that's wasn't true at last year's event as I think you would agree if you'd been there.
The stuff I bought anyway was very reasonable (in fact rather too cheap in some cases - deeyem was definitely guilty of underpricing). Prices were well below what you'd pay at a toy fair, because there are no professional traders, just members looking to buy/sell/swap their spare stuff. The most popular stalls were the ones like Sal's, where people were just selling loose spares at bargain prices. Anyway, you can always try and haggle if the asking prices seem too high. There's no charge for tables (although donations are welcome) so sellers don't have to cover their costs of a table with their sales.
I hope no-one is put off because they think it will be expensive. You don't even have to pay an entry fee!
