Got lucky on eBay yesterday and got a 2001 Taylor 414ce without electronics. I always assumed that such a guitar would be a 414c (no "e") then, but Taylor confirmed that it was ordered that way and it is factory

labeled 414ce. Never seen one before, but reportedly they do exist.

It wasn't as cheap as I was hoping for ($913.25 plus $50 shipping), but given that it will continue to age without being outdated -- the main advantage of having no electronics in an acoustic -- it will probably stay with me for a very long time, so I'm quite happy with it.
