ravenwolfe, everyone's tastes are so different that it would be very difficult to have a so called master list for people to shop from.

Like Harris says, everyone's tastes are so dramatically different, there's no way to tell you what you should buy. My own purchasing decisions are based on what members here are praising. Then I look at the reviews on tobbaccoreviews.com and read these reviews carefully to get an idea of what the tobacco might taste like. I check it's nic strength, etc.
There have been several blends that others loved that I felt only 'meh' about. So I would recommend that you start with small 1oz purchases of the main tobacco blends. Some examples are below:
English (with latakia): Dunhill's Standard Mixture, Dunhill's London Mixture, GLPease's Westminster, Esoterica's Margate
Balkan Blends: McClelland's Grand Orientals: Yenidje Highlander, GLPease's Caravan
Oriental Blends: Presbyterian Mixture, Rattray's Red Rapparee, Robert McConnell's Oriental Mixture
Virginia Blends: Rattray's Old Gowrie, Rattray's Hal o' the Wynd, GLPease's Embarcadero
Virginia Flakes: Samuel Gawith's Full Virginia Flake, Rattray's Marlin Flake, Butera's Royal Vintage: Matured Flake
Virginia/Perique Blends: A&C Peterson's Escudo, GLPease's Haddo's Delight
Virginia/Burley Blends: Esoterica's Stonehaven, Solani's Aged Burley Flake, Gawith and Hoggarth's Bob's Chocolate Flake and Best Brown #2, Samuel Gawith's Best Brown Flake
Aromatics: I like
Pipeworks & Wilke blends as well as Newminster aros, but there are lots of recommendations to be found on this forum.
Choose one from each category - read reviews on tobaccoreviews.com and see what the general consensus is and various reactions to the blend. You kinda have to use your gut instinct on separating truth from fiction when reading the reviews, but they are still helpful.
