This - love these triggers. You can order them just as a trigger shoe or as a trigger with the bar attached. I ordered my first one with the trigger bar attached but ordered all subsequent ones without it because it is very very easy to install.
Pair this trigger with a 3.5 pound connector and you will love it.
I don't consider myself cheap, but $115ish for just the shoe is pretty steep.
What's the difference between the DAT and TAC trigger shoes?
