Where can I buy high quality juices?

I've been using Backwoods Brew for over a year now and they are great, but I wanted to try some new juices and experiment a little. Can anyone recommend a vendor that sells similar quality juices? I really don't like the chinese/dekang stuff.

I'm into tobacco flavors more than anything.

Edit: to clarify, I'm looking for a vendor that makes their own flavorings. I've found that most juices seem to taste similar regardless of vendor because they are all buying flavorings from the same supplier. I'm hoping that someone here can point me in the direction of something unique and high quality.
