Again, I personally would suggest the directories listed on GetListed.org. If you haven't gone there yet, here is a list of their suggested directories:
- Google Local Listing
- Bing Business Portal
- Best of the Web (as Robert suggested)
- Hotfrog
- Superpages
- Yellow Pages
- CitySearch
- Yahoo (again what Robert suggested)
- Nokia
- eLocal
- FourSquare
- Yelp
- and a few others
These are all "trusted" and "SEO friendly" in terms of your original question.
Getting listed in these or other directories is not necessarily going to make you rank higher; however, they will hopefully drive some additional traffic to your site.
When you say, "high quality", what are you actually asking? If you are talking about PR and DA or passing link juice or whatever... it is going to depend not only on the directory, but also the page that you are on in that directory - whether Google indexes that page, how many other businesses are on that page linking out (diluting any link juice), etc.
As Nakul stated, you should be listing your business where your customers are. Are your customers going to be searching for you in the Yellow Pages or in a Google/Bing/Yahoo business directory - maybe? Are they going to be searching for you on DirectoryBin or WorldSiteIndex - I guess I'd doubt it.
With the time you are spending researching directories or even getting listed in these directories, you could be spending creating good content that will naturally get linked to and shared on social. My advice - create good, shareable content and engage with whatever "community" your business has. When you have nothing else left to do, then get listed in a few legit business directories.
