Hmmm.. when it comes to CNC, anything I buy now has servos. The occasional brownout we get here has made that feature (the machine knowing where it was when it cut out) worth its cost many times over.
Im just dealing with lasers on that, but I would kill for my printers (like the $30K flatbed) to know where they cut out at when connectivity was lost) to have the same abilities. IF I was running any machining centers instead of farming that stuff out, I would be all over it at just 2K more. I think over a year or 2, it would pay for itself.
Although, entry prices and budgets are very real to me as well. Im looking at a 9K label printer right now. A freaking inkjet label machine... that can spit them out at 8 a second. It will be super helpful, and drop some costs, but thats a heavy investment.
