I never met a Gitane I didn't like, but I probably wouldn't buy a new one even if they still sold them in the U.S.
I would love to have a Rene Herse racer.
If I was forced to get a new bike, it would probably be a Richard Sachs:

But I would never commute on it--too nice.
I like some of the ANT bikes
http://www.antbikemike.com/ and I like what they're doing.
