If it's in reasonably good condition, and you have 2-3 mags with it, or any other extras, possibly $400(ish). If not, a bit less. I don't have a Compact, but 2 full sized Beretta's and one Stainless Taurus 92 with a match tube, and a an M-9/22..
The new ones from Beretta are running around $6-625 with an actual list of around $7. The Chiappa 's are $549 list( for both std. & compact) but I see them for $500 most places. Like I said I have their 22 M9 clone,..they are just as good function wise as the Beretta's IMO. I had an M9A1 stainless in my hand at an LGS recently. Right after I put it down someone who walked in, saw it and out the door it went. If I were you I'd keep it...
