Re: pricing, I think with this kind of thing it is never going to be particularly cheap. If someone is on a tight budget they'd like use a standard machine with 8mb expansion and a scart cable.
As far as reloaded goes this is something that has not happened in 20 years, it is up to Jens how to price it and balance price with demand. It is never going to be cheap to design/manufacture sell something in a very niche market no matter how cheap the components are. I'm just thankful someone is doing it because it may have never happened.
