Your statement begs for a respone.
I've been a Compucarve/CarveWright owner for over three years. In fact I now have three machines and have logged probably close to 1000 carving hours. My total repair bill has consisted of a new feed belt...about $45 IIRC and that was because I inadvertently used a board with a void on the bottom side. I have also wore out the flex shaft on one machine....about $75.
My secret? Well I read the manual three times before I started using the machine, I clean them pretty religiously, and I have a good understanding of how the machines work. I really don't think that's asking to much for any machine but to each their own I guess.
I also only load straight jointed boards or use a straight squared up jig. GIGO
As for building your own CNC, if you have the technical ability then by all means go for it. If you're looking to save money by building your own, then I caution you to rework your figures because I have read horror stories from some who have went that route and have spent more than I have on three machine and they still are not operating. In the meantime each of my machines has not only paid for itself but has contributed to other shop purchases.
Lastly I have never heard of a store putting a return unit on display, at least not a Sears store. They are given specific display models for that purpose.
No hard feelings, just wanting to set the facts straight for others who may be reading this from someone who has logged a lot of hours actually using one.
