Anyone using MSD Dynaforce Starters

I just used up my second Powermaster Ultratorque starter. They only seem to last about 2 seasons. The MSD starter looks a lot like it and since we sort of built my headers around the Powermaster I'm afraid to try anything that looks much different. Has anyone used the MSD? Do you think it is just made by Powermaster or is Powermaster the Chinese knock off?

We have it on a couple cars. Best thing we ever did to any starter was go 16volt on as much as possible. That and wire direct to starter and stop doing that jumper wire crap that people started with the Chevy type starters years ago when heat soak was an issue.
