Very lightly used Behringer 2600 Analog Semi-modular Synthesizer. It is mounted in a beautiful wooden stand from Synthtoys on Etsy. Currently mounted vertically, but can be mounted horizontally ($135.31 value including tax and shipping). It looks like new, used very little, and works great! Tech specs can be found on Sweetwater's website.
