Yamaha DTXpress/DTXplorer/DTXtreme

First of all, thanks to all who stop in to read this, 'cos this might 
be a long-ish post ;)

I am currently living in Korea.  Before coming here, I had played 
drums for a grand total of 7 months, and totally loved it.  Made some 
good progress, if I do say so myself....  anyway, now that I'm here, 
I really miss drumming!  I'm considering buying an electonic kit - 
something small and quiet (apartment living), something to continue 
working on my skills and practicing until I go back home.

It's a money thing.  Here, it's gonna cost me a fair bit more than it 
would if I were back home (but if I were back home I wouldn't be able 
to afford it anyway, ha ha ha).  My question to you DTXPRESSers, and 
other electronic  drummers out there, is:  

IS IT WORTH IT?

I've tried it out at the music shop, taken her for a spin, if you 
will.  I like the variety of sounds (polyphony?), the fact that one 
can customize kits, MIDI it to a PC, record, edit, all that jazz.  
The thing is, I'm not real crazy about the feel of the rubber pads, 
the static nature of the "cymbals"...  Yes, I'm looking for something 
to practice / learn on, to "get the groove", so to speak, but I don't 
want to get too used to a certain 'feel" and then have to re-train 
myself to play an acoustic set when I go back home.  Is the re-
adjustment that hard to make?

I'm probably gonna do it anyway, but I just wanted to get a few 
thoughts from some people who have more drumming experience than I 
do.  Thanks!
