Well... I only used one of the systems.
I opted for an AmigaOne in 2002, but it screwed up and ended up unrepairable.
I wasn't too impressed with it, so I'm sticking to classic amigas until a new amiga i like turns up.
Pegasos II looks impressive, and bplan seem a more professional company and better customer support, but I really want to see AmiDelf's Amiga 6000 project take off :-)
