You can check out The Angel Company stuff at
www.theangelcompany.net. It's a company that is run on a home-based demonstrator system, similar to SU. Stamps are rubber, but unmounted, and you use acrylic blocks. This year TAC has also launched its own line of exclusive papers in several sizes and is branching more into scrapbooking and papercrafting instead of strictly stamping.
HTH with more explanation. ;-)
