I've seen them on sale for around $100. Primary Arms has them on sale frequently. For a simple 3.5lb drop-in trigger, it's pretty good for the money. Much better than a mil-spec trigger and unless you are a trigger snob or compare it to a $200 Timney, I think you will be pretty happy. There are quite a few triggers in the price range so read reviews and pick one. Here's a good article I read about AR drop-in triggers: http://www.thetruthaboutguns.com/2016/04/jeremy-s/ar-15-drop-in-trigger-roundup/
I've not personally owned one but have heard a lot of good things about them. Some of the 6.8 guys seem to like them quite well. I wouldn't hesitate to try one but I like 2 stage triggers in my ARs.
I have a Hyper Touch that I got from Brownell's. Not match grade, but a huge improvement over the standard mil spec one in the lower kit. Only about $90.
I have that trigger from rise armament. I really like it. Night and day difference from my other mil spec trigger. Only complaint was it didn't come with the pins.
