I had a .44 Desert Eagle as well. Sold it for $750 just before shipping off to boot camp. I think I paid about the same as I sold it for. Now everyone I see is $1200 or more.
Wish I still had mine; though I gotta say-I sure don't miss feeding that thing.
Regret not buying:
1903 USMC sniper rifle from the vet that brought it home. I was out of work at the time.
1903A4 sniper rifle at the Frederick show for $75. Still kicking myself over that one!
Regret selling:
.44 Auto-Mag. At least I made money on that one.
Winchester model 94 Legendary Lawman. It had the most beautiful stock I have ever seen!
USMC built M1A that I bought off of a Marine Corps team coach who was going thru a divorce. Got my first 10 point LEG with it.
