I wouldnt recommend a 426, as the stock sleeve is used and gets very very thin when bored out that much.

Try the cycle trader www.cycletrader.com E-bay, and all the message boards. Plan on spending quite a few hours in front of the monitor, and take good notes. I live in California, and bought my 400EX from Ohio. Even after shipping, I saved quite a bit of money. Forward Air is the least expensive way to ship that I've found. Under $200 for mine.

There are lots of 250R's out there, you just have to look.
