Thanks Dean. Of course I asked before checking your site again, so oops.
It looks like yours is a real contender, although the price is a little stiff for a slip-on. Especially if I have to drop another $100 for the bracket. I'll ponder that awhile as I continue my research.
Any other suggestions from the others? The only one I think I've eliminated for sure is the Jardine. Probably too loud and too many comments on poor quality here.
