I haven't dealt with them, but many posters give high marks to SWFA. They always have an ad in Shotgun News. I have a Long-Range 8.5x25x50 side focus on my 700VS in .308, and it performs well. This is unquestionably the most upscale firearm I've ever owned, as I'm usually waaay too cheap to spend this kind of money on myself (three teenagers at home, you know). Hope this helps
