Don't know what you are comparing to, but Probe tends to be the same as SRP, Wiseco Pro-Tru, etc, and some applications are a good bit cheaper. Not much out there in a cheaper Forged piston, only Keith Black's forged head relief line or TRW/Speed-Pro Forged are a little cheaper.
If you are comparing to "Hyper-pathetic" pistons, the hypers are not even close to the same strength.
I will not put hypers in anything I expect to run hard.
