Minifreak isn’t that small and not a fan of minikeys. Also doesn’t really sound Juno to me.
I’m not into new Roland either. (thinking about returning the MC-101 I got 2 weeks ago).
Also I thought the System 1M had no support for Juno 106, only a few mono synths?
Checked the Electra One website. Is it still for sale? No buy button, no dealer list, nothing. 
Looks like the preorders for the last batch are about to start shipping.
People pretty frequently buy and sell on that forum. Definitely keep an eye out.
Sorry you’re right, it looks like the System-8 might be able to do Juno but not the 1M, I actually thought it was just a module version of the same machine that’s on me
