Costner's in Bedford has several for sale. One is a FEG clone at $499, one is a used MKII at $750 and there is a FM (Argentine licensed model) for $400. The others are all higher and newer.
Ouch $499 for a fake Hi-Power, that's Costner's for ya. They can be had for way less than that.
IAMMO - I think they are in Kentucky - is peddling used High Powers and clones. Check them out online.
