In my opinion, Mount Baker is a good place to start, but you may find some who don't like their liquid. I would pick up a few samples before heavily investing in large bottles though. The nice thing about many of these vendors is that they allow you to customize your juice. You can decide not only the strength (which is standard), but also the ratio of PG/VG and so on.
Of course, if you end up ordering the "non-gourmet" liquid and enjoy vaping it, there is nothing wrong with that.
In the end, it's all about experimenting. Vape what you enjoy and enjoy what you vape.
