I've got a CO, plus I should have the Random Sampling tomorrow and I've owned the Harmonic Oscillator in the past.

I don't know what your friend was comparing them to, but the Verbos modules are some of the nicest I've ever used. The panels are very heavy, which gives them a very sturdy feel. The pots and sliders are all very high quality and the sound is to die for.

You get what you pay for. They aren't cheap, but I would have no reluctance recommending any of their modules. I plan on buying more as funds permit.
