I also just got my Elise this week. But this is toally new to me. I've only played piano (badly) previously.
I personally don't see the point in spending seven times as much for an instrument that does exactly the same thing as the Elise. I mean, what would you be getting? OK, maybe it'd be prettier, but what else?
Easy transposing is the main reason I chose Hayden. And It's already coming in handy playing tunes with my son. But I can see that the small number of keys is very much limiting this feature. The main reason I'd want to upgrade in the future is to get more keys.
I'd be much more willing to spend €2000 to upgrade to an ugly 54 key hayen than a pretty 34 key one.
Getting a beautiful hand-crafted instrument is just luxury though, but beyond the discussion of $2000 instruments.
BTW - I'm kinda glad my Elise is butt-ugly. Because I didn't mind writing the notes on it next to the keys with a paint marker (I am a complete newbie). Something I would never consider on a "nicer" instrument.
