I have bought loads of gear off Roy over a period of time, in fact he's altered some boards to suit applications we use.
Can't speak highly enough of the guy. We found a very obscure fault with certain machines running with certain computers that was flagging intermittant faults.

Roy came down, spent a full half a day with scope etc until it had been sussed and rectified and that mod is now fitted to current boards.

We used to use some American boards but had that many problems we just gave up on them. In fact I just unpacked the last new board that came about 4 months ago from the US as a replacemant and one chip was fitted with two of the pins folded up underneath.
