Lathe and tire machine opinions

Buying some tools for the shop, ordered up a transmission jack today. Should be in tomorrow, OEM brand from autozone. $280 after my autozone points discount. Been scouring the list for a rim clamp tire machine and a digital style balancer. Ran across a guy that owns a tire shop a few towns over selling a mts 2010 rim clamp tire machine. Does up to 22" wheels, said its around 10 years old, only selling it to upgrade equipment. Asking $450 for it. Then he mentioned that he is also selling a brake lathe. I think it's an Aamco brand. Comes complete with all the hardware, cutters and dies. (His description of the parts). My one son is working at a tire shop, and both have experience with operating the same model brake lathe. He wants $500 for the lathe. I am not sure whaw the value of the lathe is, the tire machine I think is a good deal at $450, but more familiar with the coats brands. Does anyone know if its a good deal on the lathe? My buddy said that nowadays none of the newer rotors or drums are turntable, that their all a one and done thing. I'm not sure that's accurate. Can a guy turn flywheels on a brake lathe? If its something that I can get use out of regularly I would buy it up for sure along with the tire machine. IMG_6472.jpg
