Sorry, haven't played one. But, if you need someone to talk you down:

No buy!!! No buy!!! Martin Guitars bad!!!

(That didn't work. Did it?)

But, seriously, if you've just gotta have another 14 fret slope-shoulder D, do yourself a favor and check out both Collings' and Santa Cruz's versions before shelling out 2 large for the CEO IV. It's probably a great box, (Only kidding about Martin Guitars being bad - I have three of them.) but I wouldn't want to buy it and then find out a year later that the Collings or SGCC model sounds a lot better.
