I have a Rifle Basix in one of my scouts and a Timney in the other.
The Rifle Basix is a great upgrade with a cleaner break than factory and a much lightened pull. It included the trigger and a lightened spring and was a simple drop-in,it was a great price a few years back from Brownells.
The Spec-Tech is vapourware as far as I know.
The Timney is a great trigger, fully adjustable but expensive and installation requires metalwork to get the safety mechanism tuned properly as well as inletting the stock to some degree.
I have also cleaned-up and lightened factory M77 triggers myself both MKII and the recent LC6 but I am unsure of your skill level.
Buckmastr is right on the money, any reputable gunsmith can tune that factory LC6 to put a smile on your face for around 125-150$,or conversely, if you dont wish to be without your rifle for any length of time order a Rifle Basix from Brownells for around the same price landed and do it yourself.
