This is getting to the point of my post -- how did you find out that Henderson's Lineup has an excellent reputation?

I can't easily take minimum three days (+ possible extra in case of trouble) to get work done.

How can I find a place that's nearer to me that also has a good reputation? I can find lots of places near me but identifying their reputations in a trustworthy way is really hard.
