I have a G-1 Extreme and really like it. Hard hitting, really nice, comfortable synthetic stock and very accurate. I got mine at Walmart awhile back, they were selling them for $125
The one piece mount that comes with the rifle is a good solid mount, I believe it's actually a leapers. The Centerpoint 3x9x32 scope that came with mine is still on the rifle and doing just fine. I've taken my share of starlings and squirrels with my G-1. The other nice thing is that CDT's trigger drops right into this rifle :)
I believe Brandon is correct,,,, usually when you sign up for the buyers club they give you $20 bucks off your initial purchase.
