This is probably the best place to go for Smithy support as a forum and think tank :
http://groups.yahoo.com/group/smithy-machines/
The guy that runs it is an electronics engineer and prototype machinist. He used to participate to my 3-in-1 Yahoo! group very frequently until he took the plunge to setup his own group.
As a plus he references his experience with the Sieg mill from Grizzly, Super X3, I think it is. He converted it to his home-brew CNC, off his separate web page full of photos of his projects, both Sieg and Granite.
Want to know about the Smithy Granite 3-in-1, go to his group. But he covers all the Smithy machines.
Biggest problem with usenet, ( rec.crafts.metalworking ) via PC is trojans. Lost a hard drive that way. Google Groups is safer. My old WebTV was safer doing usenet.
(This thread is a bit dated. I do not stop by frequently; just noticed the topic. I am impressed very positively with CNC Zone .)
