Depends.......do you just want a "lighter" trigger or do you want a "good" trigger. Lighter alone doesn't mean good. In my opinion, BX triggers are just terrible factory triggers, with a lighter pull.
GOOD triggers have no take up, no creep, no grit, break like glass and have no overtravel. The pounds or ounces is does this at has no bearing on "good". So again, do you want light or good, or both. You don't get both in a blister packed $60 trigger. A GOOD trigger surprises you when it drops, because you didn't "feel" it doing anything before it did, other than the pressure you applied.
Brimstone or Swamp Fox are the best bang for the buck. You get a really nice trigger for fairly low dollars. You just have to do without your trigger group for a few days. Never really understand why someone can't do without their 10/22 for a week........but that's just me.
