I have two, one is for sale. They are a good design, but I can't really recomend them. The older funkier one is a pretty good site, and fairly practical. Other than no longer being made, tehy were a tad cobbled togethr out of disimilar materials and such. didn't afect function, and I still use this site. It came out whne the Fat bow, naildriver site was all the rage. In comparison the SS had some advantages, but the Tox was much better made.

Since then many good sites have come along. I have their recent model, and it is a much more complex instrument basicaly some of the same manufacturing issues. The one I have is loose in one fitting, but they said they would fix it if I returned it, which is nice since I said I had bought it on ebay. They make a bunch of really nice stuff.
