Since I'm cheap by nature, all of my guns fall into this category!!!

I set a pricepoint, and cherrypick when something drops into that range. Been able to land some CZ's, a Beretta, a couple S&Ws etc, at or below $300, and not a one has been bad. Ditto a Winchester 94.
Maybe the
best deal I've ran across in a long time was my most recent handgun purchase:
Zastava CZ 99 in 9mm, an "ugly gun special" for $199 off gunbroker. For those unfamiliar with this pistol, it's a big, metal duty gun. Steel slide, aluminum frame, chromed barrel. Gun seems to be a cross between a Sig P226 and a Walther P88; it looks A LOT like an older West German P226.
As far as I can tell, the
only "ugly" issue is that they seem to have used a watercolor paint on the frame

, it comes off so easily. I used some alcohol preps to wipe the gun down, and it took the black finish off.
I used my aluminum black on the resulting white metal, and it looks fine again. The only issue is that you have to scuff the aluminum to allow the black to take hold.
Outside of that: the slide is milled steel and has a nice blue finish, and to the casual observer it looks like a Sig. Barrel is pristine. Trigger is very similar to a DA/SA revolver in feel. Very tight groups, has old/dead night sights that give a good 3-dot picture. Has a proprietary magazine, that is basically a Beretta 92 mag, with a notch cut out on the front (I tested this out, and Beretta mags function perfectly if you make the cut). The controls are similar to a Sig layout, but this gun combines the decocker and slide release into one lever instead of two (think Sig without the decocker, just slide release); and the controls are ambidextrous.
And when I say it looks like an old P226, i'm not joking. I've read posts on Sigforums where Sig owners were fooled in gun stores, until they took a closer look; and recently when I took mine to the range, my buddy asked me when I got "a Sig".
Can't beat that for $200.
