The Joes 2006 is a great machine. I built one about a year ago and it works really well.
For the acme rod, I would suggest you get the double start 10 or 8 TPI as it really makes a difference in the travel rate. I run at about 100-120ipm while cutting with no issues. For routing wood, this is about the minimum I would run.
Initially I purchased 10tpi single start rod from Fastnal for about $35/6' length. This limited the travel speed to about 80ipm max and I ended up getting the 10tpi double start from Motion Inc for about $120 each (ouch). If you can get the rod from McMaster-Carr, you will pay less than 50% of that price.
I am located in Burlington, Ontario.
