I've decided my next purchase is a Mackie controller. Not interested in alternatives unless they are as well LCD'd well as as the Mackie rig. My question is ... new or used? I can afford to buy it new. I am not afraid of eBay - lots of good transactions, and only a couple of marginal ones. I can save about $300 buying used, but I don't want to go there unless these things are robust enough to act like new, even if a couple years old and handled with less-than-kid gloves. While I'd love to run over to GC and walk out with a box under my arm so I can play with it tonight, I'm not willing to pay a big premium for that. Have you had to have your MCU repaired? Should I be concerned about how much warranty is left on a used MCU?
