The $200 trigger is worth it when you are competing, or the type of shooting you enjoy doing requires it.
But you can get a better trigger for not much, depending on your needs. Other than my "shoot golf balls at 200 yards" set up (Hiperfire trigger, 2.5lb pull), I've got 3 lowers all set up somewhat similar. Two have PSA EPT triggers in them, and while certainly better than average milspec the EPT gets even better when paired with a low power spring set. Even if you were to just replace the FCG and springs this way, it is a $40 upgrade. The third is my latest, and how I'll be doing all my other lowers. I used a JoeBobOutfitters "enhanced" LPK. Comes with a nice ambi safety w/ a 60 degree throw option, has a "no grip" option, or a "replace grip with Ergo grip" option (my choice, what I'd do anyway), and the trigger is better than the EPT trigger (sample size of 1. anecdote != data) If you are building up a lower and buying a LPK anyway, this option (w/ Ergo grip) is about $15 more than the basic Anderson, etc LPK
After that, there are various drop ins from ALG etc. in the $60-100 range (others already mentioned up thread, but also check out the Hiperfire EDT and its ilk), but any more than that and you may as well go for broke and jump into the $200-300 range (if you do I *really* like my Hiperfire 24E).
