I've been very intrigued by a couple of what I'm guessing would be considered hybrids - the Marin Muirwoods and the Swobo Otis (or Dixon when I throw the wallet to the wind). Any opinions on these?

I have a pretty short commute with one nasty hill. I like the notion of the internal hub on the Swobo, and they seem like they may be a bit better built than the Marin. But the Marin seems like quite a value. Of course the nearest dealer for either of these lines is 3 hours away, so this is all just based on pretty pictures on the web.
