Torque multiplier for truck lug nuts

Truck World sells Cheater Wrenches? Or the X12? Or generic torque multiplier wrenches? Any idea how much they sell theirs for?

 

I've looked at those on eBay and just not sure about a lot of them. Usually no warranty, torque output is not 1:78 like others and they come with two sockets, usually smaller sizes. It just seems odd to me that there are only two real "brands" of these wrenches. The X12 has 1:12 output and costs a ton. Cheater Wrench looks promising with a lifetime warranty, sockets of varying sizes but it is still over $100. It's what I'm leaning towards but was hoping someone here had experience with that particular one before I bought it to make sure it's worth it. But my guess is they all come from the same factory somewhere anyway, so if you're happy with yours I'm guessing this Cheater Wrench will work out.
