Over priced yes. When I was still using the small engines I had more then one. I personally never had a problem with them. When the FX came out I saw a lot of the chrome peel problem but OS made good on all of them, very good service. There can be teething problems with all new products that weren't discovered until after they hit the market, that's when the service of the company comes in. OS made the changes to the chroming procedure as soon as the problem showed itself and the new .46 FX became legend in the racing circle.
The new AX models are outstanding and so easy to tune. But that over priced thing got to me so I gave the SK line of engines a try. There design suites my needs perfectly but like all things, they may not be for everyone. OS is the everymans engine, as long as that man has deep pockets he will have an outstanding product.
