I have a 2007 SEUC and have had no problems since the recall was done. I installed the Mono Tube kit in the front end and Progressive 440's in the rear, the bike runs and rides really nice. Would I prefer the new frame? Yes..It's really about finances. If money is not a problem, go with a 09 or 10, if money matters much at all, I really think you would be happy with a 2007 or 2008. One of the other things I like about the 2007 is the leather tour pack. In my view, it has a real custom look and stands apart from a new Limited. I would stay with a 2007 or newer to get the six speed transmission, that is a reall biggie.
You can get a extended service contract on used bikes and I would recommend it. That way you can ride without a concern. As I said, it really comes down to money, if I had unlimited funds I would have a new bike every year, I don't so I enjoy what I have.
