AirForce SuperSear from AOA (Custom Parts)

Except for the harsh AF trigger, my Stubby with the hi-flo valve and 12″ 177 barrel is dynamite with JSB 10.34 pellets. The Maddog stock lets it shoot regular 1/2″ groups at 50 yards but the trigger really sux. I would really like to lighten up the trigger quite a bit. Is this product worthwhile or worthless? Are there better alternatives that don’t include shipping the gun off, etc.? I know the deal on Custom Parts from AOA. Its $55 – easy to install and adjust I hear.

Thanks In Advance!
