I'm gonna just say, if you're looking for a basic commuter bike and you can afford that Breezer, get it.
Used bikes can be great, but Craigslist is a crap shoot. You can get some good deals, but be prepared to do a tune up on the bike yourself or spend the money to have a shop do it.
I won a Breezer Uptown EX brand new in a contest from People for bikes back in like 2009. It's a great bike and would suffice as a commuter for just about everyone.
