Oh, I can see some of why Tiptop's Buchla prices are so cheap: for example, none of these have Don's "E-bus" behind the panel. Also, take into account that passive (and some active) components used here are cheaper than they'd been in the 1970s when the original 200 came out. And it wouldn't surprise me if Tiptop had their own board fab, given that they can reliably supply BIG concerns, such as Sweetwater. And the really cool part: no separate control and audio paths...everything conforms to Eurorack's patching standards, which definitely simplifies the design of these while their primary circuits STILL have that tasty Buchla flavor.
