Vortex Sound Research

If you're using (or have used) North Coast Synthesis modules, what's your opinion of them? Been eyeing the Leapfrog VCF, and the MSK 013 VCO. Have you used those? What did you think? Did you keep them? I've heard the build quality and support are good, and that they include a schematic with the module, for easy repairs. One other thing -- any large startup power draw? (Some modules require more on startup than their 'resting' power). Thanks for any info!
