Recommendation for body shop/collision center

I have a 07 328xi coupe and I need some work done on the passenger side quarter panel (there's a dent and a pretty deep scatch). It's been a while since anyone has posted about body shops/collision centers, however I would like to know if anyone can recommend the best in the DC, MD, and VA area (I'm not worried about doing things on the cheap I just want to make sure it gets done right the first time). Please weigh in even you agree or disagree with someone else's post I am trying to get as much input as possible so I can make the most informed decision. Thanks.

When my 335i was damaged I used http://www.wagonwork.com/ they were expensive but did good work. The other guys insurance paid for everything so I didn't really notice. They did scratch one interior trim piece while working on my car but they fixed that for free once I brought it to their attention.

Try EuroPros in Gaithersburg, they are not the quickest but Jack does excellent quality work

Has anyone heard anything about Russell BMW Certified Collision Center? It's the closest "certified collision center" in the DC area.
