It just how the community is. I've spent far too much money on my Amigas and almost everything costs a fair bit. TBH though when projects are successful they do tend to do quite well (the new Amiga 1200 cases must have sold a fair bit, and the vampire 2 cards). If you go to the Amiga meetups there are loads of people there. I don't think anyone expects them to become super-wealthy.

Considering the machines are now ancient and people put a lot of effort in to keeping the hardware relevant, I personally don't mind paying the extra.
