anyone an idea where to buy a valve seat grinder (45degrees), i am not looking for such a complete $300-$500 garage kit.. just a simple afordable (read: cheap) manual grinder to get my valve seat nice and smooth again .. for the finishing i will use that valve grinding paste.
been looking on ebay but nothing of my taste there
or maybe someone has a good alternative trick to do those valveseats ?

thank you
