I've tried a few of the low priced triggers. A CMC drop in single stage, ALG single coated with either this or that, a RRA, Geissele G2S, usually on sale.
The best (at a low price point) have been a Schmid Inside from Midway, only bought one when sale was $59.99, and a few MBT-2S (cheaper when you buy 3).
With a two stage trigger keep the hammer spring, and install a low power trigger spring, and a single stage mil spec disconnector spring.
You can also cut one loop off the disconnector spring that came with the 2 stage. The trigger spring sets first stage pull while the hammer spring contributes little to pull on a two stage. A large part of the second stage pull is the disconnector. Just don't go too low though as you could end up with doubles.
A little over 2 pounds seems about best.
The Schmid 2 stage uses the trigger pin to hold the disconnector making removal EASY.

The MBT-2S has a separate pin to hold the disconnector and is a little bit of a pain to remove and replace.

For my long and heavy single fed prone AR's doubling isn't a worry.
Might not be a good idea to modify PCC triggers though.
Here's a short video of a modified MBT-2S. Less than 2 pounds.
