Does anybody have a good place for take off barrels?

My Ruger M77 Heavy Target in 22-250 is an amazing rifle but sits since I fell in love with my 22Hornet.

I need a take off 250-3000/250Savage barrel in a medium/heavy contour. I supose any .257 barrel in 1:14 or faster twist.

I have found a few new barrel makers but I figured that many 250s have been rebarreled as 22-250s so there should be some good/cheap barrels out there if I can find them.

So besides gunbroker does anybody have a good source for barrels?
