I would suggest Tip Top Audio VCOs (which I don't own):

You definitely don't want to spend money on the cheapest VCO (doepfer
A-110) as you'd be getting the least bang for buck.

I heard that some people like to remove the spring from the Doepfer
joystick as it doesn't return back to its center with the spring... it
returns a bit off center which would be gay in my opinion.

OK! YOU REALLLLLLY HAVE TO STOP AND THINK ABOUT THIS: Really think
about how you are going to handle mixing/merging, inverting, and
splitting/multiplying, and attenuating signals. Some modules have
multiple ins and multiple outs, some modules can attenuate, some
modules can't, etc. There are many options for signal routing modules.
I personally think the best way to go it to get mixing/merging modules
that don't have attenuation knobs and get one or two dedicated
attenuation modules. The reason for this is that most of the time, a
module's input has an attenuator. Signal Mixers and Multipliers that
have multiple ins/outs generally don't have attenuation knobs, but
they are extremely useful.

You need one signal multiplier that is buffered (low signal
degradation when multiplying a signal) so that you can route 1v/oct
signals to multiple oscillators, filters, and whatever else. The MX224
is not good enough for some reason, but it's GREAT for general
purposes. I have a Plan B Model 31 Buffered Multi in the mail so I'll
see if that is any better.

An A-138c is a very useful mixer because it can invert a signal by any
amount. By the way, signal inversion is one way to make filters
distort and scream.
