Actually, in the world of Analog Modular synths, the Doepfers are pretty affordable, actually on the low end of the cost scale. Check out www.wiard.com and www.synthtech.com - another affordable and quality modular is www.synthesizers.com. In the doepfer form factor, there's also www.analoguesolutions.com and www.analoguesystems.com ... but anyways, back to MIDI controllers... :-)
