thoughts on ratchet shifters?

I just looked on the Summit website, the one I had was a B&M Starshifter, model 80675: http://www.summitracing.com/parts/bmm-80675/overview/ anybody here have one of this exact model? Like I said earlier, the last one I had performed very well and I liked it a lot. I am considering installing one on my Dart. Thx

That's the same model I run. Works great.
