Stan, there are great used rifles for sale. Not all are looking to burn someone. I change rifles nearly as often as underwear... My wife would say more often.
Like most, I don't have unlimited funds for my toys so, if I want something new or improved, then something has to go. Within the last three years, I sold all of my BR, Varmint, and Tactical rifles and replaced them with BATs and Surgeons at much greater cost. I've yet to build a better shooter than the Hall S 22BR switch barrel setup that I sold on the Hide. But, I wanted all BATs for ease of barrel replacement, so I sold and rebuilt.
All three of my Halls had different head space and required sending the barreled action each time that I wanted a barrel replacement. Same with the 700s, so I bought Surgeons.
And NONE of the GAPs, KMWs, or APAs have shot a bit better than a 700 308 that Mike Bryant built for me back in 1999. He built to my specs and used Walter Birdsong's Black T finish that held up much better than any of the more modern DuraKote or CeraKote stuff being used today.
So, there are nice rifles being sold every day. You take a chance on every purchase, just as you take a chance on every new build. Not every barrel is a hummer.
Good luck on your build/purchase. You'll enjoy the sport.
Best regards,
Bill Adcox
