The Mellotron Group

Hello

I might place a bid for the Novatron that's currently on ebay.
But before I do that, I've got some questions for somebody who knows the Novatron a bit better...

What are the advantages / disadvantages of a Novatron over a M400?

Is it more stable? better sounding??

Thanks;
