Yep, that's the one, I think we are talking about the same one, two ceramic bearings on the head and on bearing at on the pulley end. I bought that one as he mentioned it can route Aluminum, brass and mild steel. I thought it would work great as I was not going to cut anything that hard.

Well I always assumed he sent me the 350S but looking at yours and the one he has listed on ebay I notice that the one you have and one still listed on ebay has a smooth polished finish, mine had a matte finish.

I do know I ordered the 350s as I had to explain to the "banker" why I did not want the cheaper model.
