I got the Whitetail Hunter II. The GD Wal-Mart deal thread has a complete listing. AFAIK, most of the Barnetts are being clearance priced. Expect bolts to go on clearance soon, so keep watching.
I like the WTHII. It's got a nice trigger, cocks easily and is balanced well. I also like the grip. Everything you need is in the package- including the cocking rope and 2 bolts. Scope is crap though. It will get the job done, but too much of the sight picture is obscured by the reticle. It's a loud unit, but don't think it's any more than other competing brands.
Most of the Barnett line is the same thing, with variations on camo being the most obvious. I'm guessing the cams are the price difference. I added a sling to mine and am looking for a new scope. I have a few different bolts and I can tell a difference in the POI between them caused by the fletching and maker, but I can put all of them in a 2" circle at 25 yds. kneeling. I'll try Blazer vanes soon.
