Hi, I did get to play one, briefly at a specialist shop here in the UK some time ago. It was a pretty high trim level instrument.
I love my two 12 strings - a rebuilt and customised '64 D-12-20 (looks like a D12-35) and a similar aged Harmony H1270.
The Collings 12 had a superb presentation (as you would expect), and the neck was lovely, but the sound from a "0" size guitar simply did not suit me!
Now, if they could put the same neck on a 12 fret dread body ....! Bye bye Martin and Harmony!
