Kind of a late response, but I just joined...
I am a long time rower on a Concept2 indoor rower. These rowers use a spinning flywheel design, far superior to any piston-based rower; which I would avoid like the plague. Concept2 also hosts a huge online rowing community, including motivational prizes, forums for competition, weight-loss, general health, etc.
Have a look around their website, which you can find by googling Concept2.
