Hi, I've got an as-new Korg microKEY for sale, the 25 key version. It's less than a year old, bought it from Long & McQuade, and still have the receipt (still under warranty!). Was around $80 new. Will come with everything it originally came with, including a USB cable. Can meet anywhere downtown this weekend/coming week, will bring my laptop so you can plug it in and test it. Makes a great little desktop companion for MIDI work, very light and portable, it was an impulse buy and I just never use it. On-board arpeggiator. See this link for more details: http://www.korg.com/us/products/controllers/microkey/
Great deal. Price is firm. Thanks!
