There was a thread on the Dickey John's not too long ago - more about the Mini Gac's than the M3G.  however, you still may want to check it out.

be sure to check out JZIMM post on Worhtington's. 

My perception is the Mini Gac is on sale thru the end of Oct.......  if you want to spring for one of those.
