AR15 trigger opinions

[rondog]

So, I have this DPMS carbine. Shoots great, but the trigger is awful. I had Bert do his best with it, and he helped it a lot, but you just can't put much of a shine on a turd.

So I'm looking for opinions on triggers. Not looking for competition, just something that will release clean and smooth when I get the crosshairs where I want them and am ready for a BANG. I'm just a target shooter, and have enough trouble getting the sight picture stable, without having to grunt the trigger over the edge while trying to hold steady.

Timney? Gissele? Other? Single-stage? Two-stage? ???

Yes, price IS a major consideration, must be affordable and not just pipe dream material.
