As far as I understood it works the following way:

If you are invited to order a unit and you can't afford it at this moment you can order a unit later. If you order your unit and all produced units are sold then you'll have to wait till the next batch is ready. But whta the guys@empeg say they want to serve all the registered persons with a unit till about end of this summer and after that come to a state where you are able to buy an empeg from stock.

Hope I'm right - anyone correct me if not.
