for 600 bucks?!?
wow considering the circuit…that is a bit of brand mark-up, isn’t it?
I would say, considering that it is made with less than $20 in parts.
Years ago I documented that seller shilling his own auctions using another screenname.
He has quite a colorful history and reputation in Hollywood.
If you only knew…
But amazingly, that IS the going price range for Moog modules.
He’ll probably end up selling it.
Attenuators are badly needed on many Moog modulars.
For Moog Music in the 60s and 70s, $20 might be accurate.
But if you can make that same basic panel with new AB quality pots and Switchcraft jacks for $20 today, my compliments to you. 
True, $20 is a bit underestimated. I wasn’t even including the price of the panel. Anyhow, what brand of pots did Moog use on their modular stuff?
The auction for the Multiples was the one that was over the top to me. $524 for a Mult!

1 MU plate. $20. 8 Switchcraft jacks. $36. Moog name upcharge $468
How many Moon or DotCom Mults could you buy for that???
Oh yeah, Vincent Gallo. 
I remember he has an account here. Blew up at me because I cracked a joke, tried to use Bob’s name for some guilt trip, then deleted his posts.
