If you're not interested in buying it, there's really no need for you to post in this thread. Too many whiny low-ballers here on MR. This is not a drama thread, it's a FOR SALE!
Less than a year. I bought it used (was used for about 6 months then) for a second one on a 60 cube. It was too much so I pulled it after a day or so and it's been sitting here ever since.
