I've had a number of different Geissele triggers that I thought were great,One of the best "bang-for-the buck" triggers, is the Larue MBT imo. It can be had in a couple of different styles (flat bow, curved, etc.), all for around $87. It's precise, repeatable, works fast, works slow. It's a two-stage and the wall is predictable.
The other 2-stage trigger I like is the Geissele SSA-E. It's difficult to find a better trigger for a battle rifle, with precision in mind. They aren't cheap, but it's typically the trigger to which all others are compared.
until I bought a LaRue MBT. To me, that is the best available trigger in the $100 (+ or -) price range and probably my favorite overall.
