I have used just about every block type target out there, and the Rinehart is the best I have found. Personally, I'd buy Cabelas generic version though. Same product, but it'll save you a few bucks. Sportsmansguide.com occasionally has factory seconds at a huge discount as well. I got an 18" Rinehart for $48 from them this summer. Only thing wrong is it has some seams sticking up. Doesn't effect the target at all.
