FW: G-TechPro Competition...

[Livolsi, Stephane]

seems to me that it would be an ideal situation for a few guys and gals
living reasonably close together to all chip in and buy 1 for the group, to
be shared.
Wish there were more audifans in my neck of the woods.  As it is, Tihol and
I have pretty much agreed to go 50/50 on all major tools.
