They sell pretty much the same items they offer on sale at Stoneleigh Spring Convention. January sale is marginally more expensive than Stoneleigh but without the fighting So given that you'll spend about ?15 to get into Stoneleigh, why waste half the morning in a scrum when you could go to a couple of good lectures instead?
The quality is fine, and sometimes excellent. It's 2nd grade wood which means the odd knot in the wood but perfectly okay. Frames are supposed to be 2nds too but you can barely tell.
