Automags.Org Online Forums - Amazing Pneumag & Invert Mini
I see them for sale on the automag forum fairly regularly.
The difference in prices will be the valve.
If its got an Xvalve (which that one doesnt) it will be a couple hundred more.
The ones with aftermarket trigger frames, many of which are out of production,
will be more money too.
Most of the ones that werent jury rig looking were around 700.00 or so
that I have seen.
