This guy sells these on Ebay. He's got good feedback. It looks like a stout unit. Seems like the drawback would be that it doesnt bolt on with a sleeve like the bro-tek and emp models. It says you could drill through your boom to bolt on or weld. I bet I could fab a sleeve up with my chop saw and welder to mount it pretty easily. The price is right, but I'm not sure if I wanna deal with the mounting issues. I didn't measure the dimension on my BH75 with 16" bucket yet either to see what size thumb I would get from this guy. Anybody have one of these?
