I'd just hold out and cruise the eBay. Having done your homework look for ones incorrectly advertised. I got a Scrub Pro Series 90cm, like new, with toolkit, grab handle, Scrub rachet bindings and full stainless steel kit for £51 inc. P&P! It was advertised as Flexiboard, with a very poor picture and by someone new to eBay, but I knew what I was looking at wasn't a Flexiboard - winner takes all.
Patience is a virtue - good luck. I agree with the others too about Argos.
