It's amazing. Following Makerbot from its conception and thinking that it will be forever before I can touch one. Then Bill of Materials lists come out for RepRaps and then there is an explosions of variants. Some really come through as solid machines, Mendel to Prusa and now we are getting into different materials. It's just not stopping. The SLA machines are becoming cheaper, there is even a movement for open sourcing an SLS machine. I can't wait to see what happens and hopefully be involved in some way.
