That looks like the 15-2 I foolishly gave up several years ago.  I paid about what you paid, only this was in the 1980's.  I shot many rounds through it, but when I needed parts Dan Wesson was temporarily out of business.  I sold it and they reopened with parts for the older models, as CZ does now, although they don't have all parts for all the older models.  The 15-2 was the last improvement and many parts are available from CZ , or many online dealers.
