I have seen another sell for $80 not to long ago, but it was "ruined" by removal of butterfly valves. I feel like there is ether none available and people pay crazy money for them (over $300), or... it is for sale forever for sub-$100. And nothing in-between /ubbthreads/images/graemlins/wink.gif
this one has a gasket with small piece missing from it. You could make a your own with gasket material, but it would take a while.
I will stop dropping the price at $120 and then just keep in the basement until someone who cares about bottom end torque comes around /ubbthreads/images/graemlins/smile.gif
