My apologies for not updating in a timely manner. I pulled the trigger on a used 4000, apparently quite old but by the pictures it appears to be in decent shape. The proof will be in the pudding when it arrives tomorrow. When I can get eyes on it I'll have a much better idea of the direction I need to go. In the mean time I've been reading everything I can about Sherlines so when it does arrive I have some familiarity with the tool.
I've barely scratched the surface and I'm very excited about this new endeavor. "Patience Grasshopper", said to self.....
