Since Worthington is about to come out with a new high pressure tank I wonder if the price of the PST tanks will come down or will Worthington just match the price of the PST. I am wanting a set of PST's really bad but if I wait will I reap the benefit of competion? I can wait about six months at the most after that I will have to take it in the shorts. Any thoughts are welcome, or am I just being cheap.
