Very rare, truly luxurious: the EMS VCS3. Here’s a VCS3A on eBay, one of the first ever. Hard to find, it will cost you a furtune in case you’re really interested (asking price is 19,000 USD). The instrument’s casing shows the “typical” VCS3 problem: a cracked wooden corner. Nevertheless, the photos are interesting, as they show how the VCS3 looks inside!
