I picked the 99-02 250 as it looked the cheapest and easiest.
I agree, and they are a great looking bike too. I can usually find frames on Ebay, but I can't afford to build a complete bike out of Ebay parts, or I'd have $7,000 into the conversion.
I need to find a good roller, or even a complete bike nearby, but I'm not having much luck.
I'll check out your build thread! Thanks!
