  1. I have endless respect for guys like this. They are having fun and exploring synthesis. At the same time, when it comes to being offered the option to purchase it as a kit, I feel about the same way as I do with most ipad musical apps (and especially those without midi). It’s cool, but it will likely never get used.

  2. I’m pretty sure completed ones will begin showing up on eBay quickly.

    There’s a pretty active DIY analog synth community — check out Muff Wiggler (hey, I didn’t choose the name) forums. Small entry projects like this one or his Weird Sound Generator provide great ‘training’ projects for folks who can then move on to a Klee! And when you discover that you can buy 2x as many modules for the money if you build them yourself, you promptly begin spending the rent money on blank PCBs and through-hole components!
