Here's my 2 Kimbers: Eclipse Target II & Custom TLE, Wilson Combat Mags, CTC Red Laser (Rosewood & Burled Walnut) Grips on both, 230gr HPs, adjustable Meprolight Tritium rear sights. I carry each in Galco FED 212 Paddle Holster w/ 2 extra mag holsters for each, plus 5 extra mags in my 5.11 tactical vest.
I've seen jewelry and household items go for pennies on the dollar, but on the guns, there's too many knowledgeable buyers there to routinely expect to make a steal. Still, it's fun.
