I'm thinking about buying a used FX 500. I've seen some of the older models for sale that don't have the power adjuster or regulator that seem to have a decent price. What am I missing out on by maybe getting one without the power wheel. Are the newer models capable of higher velocity? I'm sure even if I had one with an adjuster I'd shoot it on high anyway, unless it shot over 940 somewhere in that range.
