What about us few GN owners that swap work for parts or offer advise. But this isn't what we do for a living.
Or we would starve.  We like you buy or deal w/ vendors
And if it becomes beneficial to us would love to become a 
paying vendor. If just to support the group.
Some of us are not on here to sell,sell,sell. But to
learn,learn,learn and be a part of the community.
90% of the potential customers that contact me about 
a job or project for them. I usually explain to them what needs to be done and then let them know that a local can probably do it.  I hope we (I) am not offending.
