I own most of them..... Hood, Tipton, MTM, Caldwell, Plano, Hoppe's, Guide Gear, Cabela's, some wooden ones I cain't remember names of..... but the only ones I have more than one of are "Pelican" style from Brownell's (they're useful but I've broken one) and the Berry's VersaCradle.
I've ordered them from Brownell's and from the factory. I broke a strap and another strap got weak so I called Berry's to get price of replacement straps, the lady took my info and said she'd advise..... 2 days later a bag of 6-8 straps arrived in the mail. No charge.
I use that $#!t one everything! And will shout their praises from the mountaintops....
i like my Tipton Ultra Vise only neg is i can not drop a 3" stok in the vise i just rest it on top
but i made just two peaces that screw in my bench and for benchrest rifle cleaning those are the best
