Elektron Musical Instruments

I'm an owner of an Elektron Monomachine and it is my only piece of hardware outside of 
my computer that I run all the typical apps on.  I'm going to buy a MachineDrum in Sept... 
that'll be my second piece of hardware.  Outside of those machines, which are definetely 
keepers, I'm looking at the Vermona Drum Synth and either a Roland SH-101 or a 
MicroMoog.  I have a few questions.

I'm wondering if the Vermona will be redundant once I have the Machinedrum?  and which 
one oscillator synth is better overall... the SH-101 or the MicroMoog?  

I like that you can use the MicroMoog's filter through the input run external equip through 
it)... which I don't believe you can do with the SH-101.  However, I like that the SH-101 
runs on batteries, has a built in sequencer (even if primitive), and is cheaper than the 
moog...and easier to find...  Both sound great to me.  I have always wanted both the SH
-101 and a Moog...but never bothered...but the time has come to buy one.  

Any opinions are welcome... thank you.
