I like those guys too . They even let you pay $100 a month for a basic system , not bad . I've been thinking about getting a PAIA system . You get 2 VCOs , 2 state variable VCFs , 2 VCAs , a midi to cv converter , and each module has modulation for $450 . It comes as a kit , but , I figure if I can fix older gear then I can do this too .
