Since i am an underage student with no job atm, im on a fairly strict budget-about 500$
I have got a midi keyboard, so it can be a sound module/rack unit. I am quite heavily into programming and exploring new sounds, so the presets on the machine dont really matter.
Having explored quite alot on this site, I've made a list of possible synths:
Alesis Ion
Alesis Micron
Korg MS2000(r)
Korg microKORG(Only if i got it really cheap, as i have quite large fingers

Yamaha AN1X
Novation A-Station
Novation KS (r)
Im hoping for some opinions and/or more possible options from more experienced users, the pros and cons of those synths and general advice.
I also excuse for my bad english.
