I'm a cheap skate when it comes to triggers, too. I went with ALG for my AR.
I've had no personal experience with those. I've used the following "match" triggers in AR15s:
Eagle Arms (Coal Valley) 2 Stage Hand Tuned NM
Rock River Arms = 2 Stage NM
Timney
The RRA turned single stage after 2000 rounds. The Coal Valley "Golden Eagle" was sold before it was shot much. The Timney was okay.
The Geissele is the best of the lot, and the most expensive.
