frdave: I made the same mistake of ordering MtBaker's tobacco juices when I first started. There is only one that I think is ok, the rest of them are not good. Be aware that nothing will taste like an actual cigarette, but many of the vendors that use NETs do actually taste like tobacco.
From my own experience, I can tell you that Mt Baker's tobacco flavored liquid does take a very long time to steep, so some may not taste right up to a month after you get them. However, I was very disappointed with their Havana and their Coumarin Pipe Tobacco. The above posters gave good suggestions. Mt Baker does a lot of things good, creating a tobacco juice that actually tastes like tobacco is not one of them.
The one that I will add would be GoodEJuice. They extract their tobacco flavors in house and their prices are not much higher than Mt. Baker. I absolutely love GJ4 from them and a lot of people really enjoy their Patriot.
