One thing I'd check before buying is the extractor. If the extractor breaks it's sometimes difficult to find a replacement, and you either have to have a different type of extractor fitted, or replace the entire bolt with Remington 700 short-action bolt. Both work but add considerably to the price.
A 722 .257 with a price tag around $300 sat in a local store several months last year, because the extractor was broken. Somebody finally bought it, apparently deciding they could get around the problem somehow.
