Elektron Musical Instruments

Hi, ive been reading from this group for a while, and after finally
playing with a monomachine in person im ready to buy one. 
I want to slowly build up a nice modest setup with the monomachine
being my center piece. I plan on using a laptop to run either Live or
Reason, and then later on down to the road add either a Creamware ASB
minimax or pro-12. I do have a midi controller, but im wondering would
it be worth the extra cash to just get the keyboard version of the mnm?
Or should I just stick to the keystation I have now? It does have more
keys to it, but having the keys attached sounds nice as well.

What do you all think? I mean for the extra money I could buy a nutty
effect pedal or likewise, or is the attached keyboard really worth it?

Thanks
