repairer for K10d

Hello all
Is there anyone else i could use to repair my camera? I have had it returned to pentax but its quite expensive.
The camera shows memory card error or when it takes a photo it doesn't always store it. I've tried 4 sd cards and now pentax says it will need a new pcb! As i havent dropped or knocked the camera i'm a bit miffed at the the pcb needs changing. I know they may know best but the price is to much.

Cheers Darius

You could try www.asahiphoto.co.uk - I doubt the price will be much different though

thanks for that, I'll see what they say.
