I just found a minty SPAS-12 at a local shop for a decent price.  It has the updated safety (very important to me), the longer barrel with the extended mag tube, and almost no wear marks on the slide.  Only negative is that it has the full pistolgrip stock.  At first i wasn't too thrilled but its actually very comfortable.  Now everyone says how heavy they are but i actually found it prety light.  Has the sling and all of the chokes.  What would be a good price to pay?

I wouldn't pay more then 800 for a fixed stock. But then again I wouldn't buy a fixed stock....
