Quoted from Clnilsen:In this case I'd say the proto adds a bit more than that in this case. The kit to remake the Dalek wobble head feature alone sold for $375 here last week....
There’s a far less expensive DIY mod option that works pretty well, too. $100 vs $400. The kit sold at almost $350 when it was originally made didn’t it? That’s actually a steal now since they are no longer made.
