IMO, mint condition gear can easily go for 90% of what one paid new - *if* you got a very good price on it new and the new market value hasn't dropped. The higher new price you pay, the bigger hit you'll take when you sell, of course. Very good to excellent condition gear, 80-90%. Fair to good condition, 70-80%. But it's all guesswork at this point since the CEMC6's haven't been around all that long. If you don't want to take a hit, buy 'em used (if you can find 'em, maybe post an ISO in the YS and see what happens), or buy 'em as low as you can new and re-sell on eBay with a reserve set at a point below which you will not deal.
