it really pisses me off when i drop 550 bucks on a machine and i have to get replacement parts right away.... its happend to me on more then one rotary from more then one company. for fuck sakes make sure ur shit is made correctly before releasing it to save you and your customers headaches.. some builders have lost my gbusiness forever over this and rightfully so. when you drop that kinda coin on something it should be flawless... especially when mass produced ....
