tequilachaser,
That's a good idea, but if I was going to use an adaptor then I might as well put in the old soundcard

I want to get away from gameport entirely. Plus, the left pedal pot has a spike right near center and I already replaced it once, so I think it might be something in the pedal geometry or gears that is screwing it up.
I think I'll go for a new one from a name retailer... I've been burned on ebay a couple of times and I've come to value my personal time at around $100/hr (that's about, on average, what I pay people to do things that I am capable of doing myself but don't have enough time to actually do it myself), so even 1/2 hr dealing with an ebay hassle makes it "cheaper" to go with a regular retailer.
