I wouldn't feel too bad about not getting a shopbot. I had probably 50+ hours experience using them at techshop, and I found that the accuracy of the 4' x 8' router wasn't very good for the small gears I was cutting. The shopbot buddy was significantly better in terms of accuracy, but both had software problems. Sometimes it would start losing accuracy for no reason silently, and at the end of the run, it would sometimes spit out cryptic error messages, and you'll notice the X and Y could be off by a random amount. The software is really wonky and can crash in the middle of cutting a piece, and when this happens, the spindle doesn't shut off. Whenever this happens, the only thing to do is literally shut off the control box for the machine. If software crashes while you're drilling a hole or something and you're not paying attention, it'll definitely start a fire. Hopefully that makes you feel better about getting a non-shopbot
