I think if you will check Steve's profile (just click on the question mark above his post), that he IS doing this for a living.
Hopefully speaking for the reat of us, we are more than elated that Steve takes so much of his time to asnwer our questions. I, for one, am happy that his answers are thoughtful and complete, not just one-liners which raise more questions than they answered.
Thanks Steve, and how in the world do you have so much time to help us, while also giving time toyour Shop and your family? It must be time-consuming.......Andras
