I've bought a few things off these guys as they used to be right next door. Most stuff is ok but tends to be somewhat generic as the kits are rarely bike-specific.
I bought a full gasket set from them for the GL which they asserted was good for both the CX & the GL, which wasn't quite true; the pulsar cover gasket for a start. But, on top of that, the o-rings for the oil passages at the head were the wrong size so I had to reuse the old ones and the dowel holes on the head gaskets didn't line up and I had to enlarge them to fit.
Next time I was in I let them know and they seemed to take my concerns seriously although I never did follow up on it. The owner offered to get me another set of head gaskets but I'd already got some Honda ones. I don't know how well they respond to email questions but there's a couple of guys there who seem to know their stuff.
I did just notice on their ebay store that their mailing address doesn't look to be updated so you might want to confirm that with them.
Personally, if Honda still sells it that'll be my first choice.
