Welcome from San Diego.
What length are you planning? Primary use?
Almost any trigger you go with will be good, but the reason they have choices depends on how you plan to use it. A lot of guys here seem pretty happy with the Larue trigger and it's a great price. Worth taking a look at. I've had Geisele SSA-E and a DMR. Both are in AR-15's, but I'm really happy with either. One is on a 14.5" gun and the other on a 24" bull.
