Kaden has spotted a whole load of electric sitars on eBay:
#7353941812 is above - a Pentasystem Pentasitar. Only five strings on the guitar, and 13 on the sitar part. Pentasystem were a short-lived company producing five string instruments with some kind of fifth-based tuning system. Their homepage now points to a Phil Lynott tribute site. I'm not sure they're really going to get $2,199 for this...
#7352820480 is a vintage Danelectro-made electric sitar, with bidding already up to $2,550. #7354505876 is the same, but cheaper - a modern Danelectro Coral, on Buy it Now for $325.
If the Danelectros aren't kitsch enough for you, #7353839422 is an 'Italia' brand electric sitar, with a kind of Hagstrom/Franz Ferdinand vibe.
Finally, remember the "sounds like a swarm of angry bees" Keyboard Sitar?
#3773047368 is an electric version. Far out.
