I bought a seven year old Shopbot that was not running and in poor repair this past winter. I got a used circuit board directly from Shopbot and brought it back to life. I have found the Shopbot easy to work on; replacement parts are everywhere, and they have an excellent user's forum. They also include a good starter software package with their machines. If you add Vetric's V-Carve you will be able to do the work you describe in your post. I believe V-Carve is under $500.00.
Just my two cents.
