you can get a brand new one for alot less that will work just fine. I have a vertex and use it almost everyday and have never had any issues with it. My pro shop guy has the same exact spinner and he has also had no issues. The 1/2 hp is under $200 shipped brand spankin new. I was lucky and found mine on this board used for $100 bucks..
