I wanted to post a valve poll. The valve question is driving me nutz, and it was a short journey to begin with! Sorry if I missed a valve but these are the one's I am most familiar with. I'm trying to get an idea of the installed base vs issues. Don't know if this will answer that question, but it's the sharpest tool I got... I could post 10 options on the poll. *** There is a mistake in the numbers on the poll. "Chipsdad" voted in every category and borked things up a little. Subtract "1" from any number you are interested in.
