Hey- I just joined a couple weeks ago, happened to read that post about hardwood prices and saw your price list- I buy from Roger too! I actually just talked to him last night. Small world. How long have you lived in Louisville?
I built it from a book on Buildyourowncnc.com. With that machine I cut out the one you see in the video. The guy sells kits, but the g-code as well in case you have a cutter in your area. I really have enjoyed it, its been fun. It will cut 4'x30" but really you can make it as big as you want.
