Both Cammy and Amigakit have done a lot of good for Amiga users and the community - I'm sure they can find a way to co-operate, but Amigakit are a business in a small market so do need to drum up business and make money where they can.
In the post Power/Elbox Days of Amiga computing here in the UK, Amigakit are a reliable supplier of hardware and software products, and after-sales support that the community need.
