I have bought from him too. A ministarter for $65. For the price level it is not made in USA of course.
I had to shim it a little back from the starter billet block. And the enclosed mounting bolts was not real starter bolts, so i changed them. Not top notch in other words, but at least the starter worked properly after that and it sound very strong. I didn't expect much for that price anyway. Just thought I'd give it a try.
The seller have very good feedback on Ebay. And over at the thirdgen.org forum there are several user that recommends him too.
But Summit Racing do also sell fabricated valve covers way ceaper than $650.
I like that style a lot my self!
