I just bought one of these from Gozur. He didn't make it, but this is the guy (or at least a very similar type) that he got it from.
It seems to work pretty well. My cab is not finished, so I have no comment on mounting it yet, although it seems fairly straightforward. I hooked it up to a few PC's in my house already and it works pretty damn well. It is recognized in XP as a mouse automatically and I've used it with Mame, Mame32, and through MameWah with no trouble. Each game can use a bit of tweaking as far as sensitivity goes, but I'm guessing that is the same for all spinners??
Anyway, I have never used an Oscar or Slikstik spinner, so I can't give you comparisons that way, but I will say I'm pretty excited about it. It works, and it definitely is more realistic than the arrow keys I was using, heh

Hope that helps.
