Damn, that sucks. I was actually close to just getting that one off eBay, but won't now since I have a Tekken Hori stick too. I'm so desperate for a converter, but the only ones I could find are cheap 3rd party ones. Pelican adapters are no where to be found and are selling on eBay for like $30+.
Thanks for the link. I actually checked that out before but have yet to find any of those anywhere.
