I've been in it since 2000, I don't get to shoot much anymore due to other obligations, but I've had more fun shooting SASS than about anything else. My startup cost wasn't too bad as I already had a SXS and one revolver. I usually shoot Frontiersman, which is cap and ball revolvers, and BP in rifle and shotgun. Like any other shooting sport, you'll find the occasional A-hole, but they are VERY RARE in SASS. You can shoot side by side with World Champions and they will be giving you advice on how to improve. They will loan you their gun if yours breaks. I am always amazed at the skill level of the top shooters. They can shoot a full 24 round stage in under 13 seconds. I'm happy if I beat 60 seconds. Here's an iCam video of me shooting a stage up at Red Castle a couple of years ago: https://www.youtube.com/watch?v=yH5ixVEtPz8
That's pretty good shooting pulp. Do you have to shoot the revolvers with both hands at same time, or is that just a personal choice ?
