The shs piston being 8.50$ at ehobby and the super shooter I think is around ten.

To be honest, if you adjust your AOE on any piston (besides the some mentioned above which are utter crap, like the deepfire) it should last a long while.

Those pistons are absolute garbage.

In my eyes a piston that can go 650 FPS for 10,000 rounds is a good piston. I tried the SHS "steel piston" with a M230 spring and the pickup lug, and first 3 teeth failed after 3 shots. My gears proceeded to eat the hunks of "metal" that came off the piston. Compare that to the 3 bags of 0.30's that Prometheus hard lasted with the M230 spring.

Granted not everyone needs or wants a gun that shoots 650fps but if want to spend the money to put a piston into a gun that can handle 650fps for several thousand rounds, I'm sure it will last at least that long on a properly shimmed box at your local club's energy limits
