I purchased this board with the intention of using it for a tabletop RA4 processor, which was unfortunately never delivered. I never unwrapped the packaging, and only opened the box for the included picture. It arrived a month or so ago, and I have no need for it. It's my 2nd Model 15, and they're great panels. Easy as pie to install and adjust.
I'll set the price at a tiny bit less than I paid for it, $300 + shipping.
