I like my Rock Rock Arms 2 stage National Match trigger with Superior Shooting Systems hammer and trigger spring set. Really smoothed the trigger feel out! Less then $160 for the set up. I actually got my RRA trigger for $90 thru group buy.I think they go for $120-130 normally and spring set I think was $25 might have been $15 can't remember.
Geissele makes a 2 stage that I picked up for 135. I replaced the disconnector spring with the factory Armalite spring and got it down to about 3lbs. I am guessing thats what they do for their SSA-E trigger. Cant go wrong with JP, they are just a little spendy.
