I also have a fast ferment conical and I actually stopped using it and went back to carboys. I wasn't really very happy with it and I had problems with it getting clogged on the main port on the bottom. On a few occasions I ended up racking out of the top of it because the bottom was just a brick and wouldn't flow out. I did make some fine beer in it, but the valve situation was annoying and the fact that it is so big made it hard to move, and I had to build a new chamber for it.
I had some sealing issue with it, but I didn't care much about that. Half the time I just put some foil over my carboy openings anyway, just don't let dust and bugs get in and it will be fine.
All that said, lot of people like it and I think some people are adding a racking port near the bottom to get around the plugging issue.
There is a new one out there called the catalyst. I think it is a kickstarter thing at this point. It is similar in concept to the fast ferment but a little different in implementation.
