I bought a rifle basix LV-1 10 oz- 1.5 lb. it is the best value for them I think. I havnt ever owned a Calvin Elite, but it can't possibly be any better that is noticeable to a human. If rifle basix made that LV-1 for Wincheser, it is all I would own.
I have a Jewell in a box of stuff I got from an estate sale. It is a 2 oz target trigger. And I have bought a few regular Timneys. The Jewell is really hard to compare to the others, due to its light weight. My honest opinion of Timney is that the regular $120 trigger is slightly better than a factory trigger after I do the trigger job.
I paid $80 for the Rifle Basix from Midsouth Shooters Supply. You will need to find one WITH a safety kit or the OLD style Remington 700 trigger and rob pins and a decent spring and ball... And e clip.
