Pretty good prices and fast shipping.
Pipe quality is reflective of the price through. The clamped end of the bend, at least on all the 180's I've ordered (5) have serated marks from the bending machine clamp. The pipe is usable but not as "pretty"
I also had one 180 come at about 170. I'm talking to them now to see how they handle it.
