I've got a Sweetwater demo unit LXR-02 from Sonic Potions & Erica Synths. Excellent condition, includes manual, power cable, and a variety of plugs.

"Boutique synthmakers Sonic Potions and Erica Synths have teamed up to bring you the Sonic Potions x Erica Synths LXR-02 Digital Drum Synth. A revamped version of Sonic Potions' renowned DIY kit, the LXR-02 is a highly flexible desktop drum machine, which goes far beyond the TR-style drum machines from which it draws its inspiration. Featuring six drum voices (which are optimized for specific drum sounds), a host of modulators, a robust FX section, and a performance-oriented interface, the LXR-02 is an inspiring piece of kit that has enraptured Sweetwater’s synth enthusiasts. With its high-quality 16-bit/44kHz audio, the LXR-02 has a shockingly huge sound. And, its powerful 64-step sequencer is a blast to program! The LXR-02 facilitates sonic exploration, and you can store custom kits on the provided SD card. What’s more, a unique morphing feature allows you to seamlessly crossfade between presets — perfect for spicing up compositions! And while the LXR-02’s Digital Drum Synth features run deep, it’s amazingly intuitive. You’ll be cranking out killer sequences in no time!
