I've had one of the older (quite old now) 2 gas torch annealers that requires different wheels for most different cartridges. Very well made and heavy and slightly hard to adjust the two torches to get the desired annealing. I spotted the AGS several years ago and really liked the way it functions and its cost of $200 (much less than the older one!). I ordered one and it came so quickly from Serbia I could hardly believe it. It works perfectly with the case arriving at the rotating platform and the annealing delivered by the speed setting and the flame setting. So simple and yet so effective and I have corresponded several times with the guy who makes them. I don't remember using my older one since I got the AGS. Of course, now with the tariffs who knows? Annealing extends the case life and uniforms the loading.
