WTB: Martin Logan lx16 or motion 15 bookshelf speakers

Looking to buy Martin Logan lx16 or motion 15 bookshelf speakers to match other ones I have . 44202 in Ohio or shipped. I have a single Ascend Acoustics Sierra 2 in satin espresso that I could trade also for the Martin Logan. It has the RAAL tweeter that can be horizontally or vertically aligned for center channel.
