yes, if i had the money for parkers at the time i would have gone with parkers...but SMCs are 2nd best in my book next to parkers....my smc's still has no leaks what so ever....my GC's leaked right out of the box, the 250s...the 450s are great valves, the old 250s are crap though, the new GC250s with the blue tops are great, my buddy has them and he hasnt had a valve leak for 6months now
