Disklavier

I haven't bought one yet, but I'm looking at the DGA1XG for 13k.  the 
price seems a little high.  It's the 4'11" acoustic with disklavier 
player.  I like the size (since I have limited space) and the sound 
is great for a small piano.

I'm torn for a few reasons; (1) this model doesn't have the ability 
to use headphones or record which a digital piano would and I'm 
afraid this will become a 12k exercise bike (not used) without those 
features.  (2) I don't know if I will like a digital piano (maybe I'm 
a traditionalist). (3) as technology marches forward, will i be able 
to upgrade the disklavier or will it become an 8 track player?. there 
are still folks who collect piano player rolls. 

What do you all think, any regrets?
