In a few weeks, my two 22U cabinets will contain the following 
modules, leaving 5 spaces:

1  Q137	Power Control (rear)
1  Q103	DC Power Interface (rear)
1  Q142	Pedal Interface (rear)

1  Q104	Midi Interface
1  Q105	Slew Limiter
5  Q106	Oscillator+CRS
1  Zeroscillator
1  Q141	Oscillator Aid
1  Q161	Oscillator Mixer
1  Q107	State Variable Filter
1  Q150	Transistor Ladder Filter
4  Q109	Envelope Generator
2  Q108	Amplifier
1  Q110	Noise Source
1  Q111	Pan/Fade
2  Q112	4-Channel Mixer
1  Q116	Ring Modulator
1  Q117	Sample/Hold
1  Q118	Instrument Interface
1  Q123	Standards
2  Q124	Multiples
1  Q125	Signal Processor
1  Q130	Clipper/Rectifier

I had originally planned to fill the 5 spaces with the following 
modules, but have been wondering if I should go for some non-Dot Com 
modules instead. Are any of these modules must-haves in a 44 space 
system? I don't plan on using it in stereo or surround unless it 
grows at least one more 22U cabinet. Any suggestions / 
recommendations for or against 3rd party modules would be 
appreciated.
 
2  Q108	Amplifier (Is there an advantage to having 3 or 4 instead of 
only two?)
1  Q115	Reverb (I have an Alesis MicroVerb and a Premier 90, but 
they can only be used on the output)
1  Q125	Signal Processor (do I need more than one?)
1  Q147	Distributor (any advantage if I have two Multiples?)
