If you're looking for a workstation/synth, that Triton Le is a great place to start.
It will more than suit your needs if you're just getting into a home based set-up.
...and....you still have the portability.
You're gonna hear Korg this, Yamaha that, Technics this, Gem that....
It's gotta be comfortable for 
you, and it's gotta be something where you don't have to read a War & Peace manual, to get a sound out of it,(you said you didn't know a whole lot about this electronic stuff), so don't make it any more difficult for yourself.
Like I said, the Le is more than ample for you needs.
Me...I use an old T3 and it more than does the job.
Good Luck in whatever you choose.
