Check out www.xtremestabilization.com and look at the x3.

It is basically like getting 3 different length stabilizers for the price of one. 6.5" 8" and 12" are the lengths it can be set at. They come with the full set o weights as well so u won't have to guess like the b stingers... They utilize a super light carbon rod and a heavy end weight design for a very high front of center weight ratio.

They work on the same principles as the b stinger, but are more adjustable(different lengths and multiple weights) and they are cheaper! Double whammy IMHO.
