I picked up a Daewoo DP-51 recently in a trade for a couple of C&R rifles that no longer interested me.
Its proven to be an interesting gun, similar in many respects to the S&W semi-autos.
It allows DA, SA, or a third mode. In the third mode, you cock the hammer in the SA mode, then push it forward. The resulting DA trigger pull feels very much like a SA trigger pull.
Mine is nicely finished and very accurate. I haven't fully mastered the trigger pull, yet -- which isn't bad, and suprisingly light in SA or Tri-action mode. (I have a number of tuned handguns, and this one hasn't been tuned, yet.) I've seen nothing in the gun that I'd called cheap -- it all seems to be forged and milled.
A friend was shooting it the other day at one of our IDPA practice sessions, and was shooting VERY SMALL groups with it. I think the gun has good potential, and after I get the trigger smoothed on mine, expect it to be a good gun.
I don't know about parts availability, but one plus of the gun is that it will accept S&W 59-series high-cap mags. There is a small gap between the bottom of the mag and the bottom of the grip, but nothing particularly unsightly.
I don't feel I got the short end of the trade. (Mine came with a custom IWB holster, mag holder, carrying case, and 5 mags, 4 of them 15-round Mec-Gars.
Century has their on sale this month for $229, fullsize or compact. The full-size in reasonably compact. You'd be hard pressed to buy a better gun for the money.
A friend of mine who has an 01 FFL bought one a year or two ago, and immediately sold it to a customer -- who is tickled with his.
