Exploring Bordeaux on a Budget

[neo-oeno]

While my attempt at a clever palindromic handle was thwarted by one letter (curse you "o"), hopefully my pursuit of a wider knowledge of Bordeaux wines will be more successful. I am on a limited budget, but am very interested in becoming more familiar with the offerings of Bordeaux's vineyards. I would greatly appreciate any recommendations for wines in the $15-20 range, though I realize that my monetary lmitations may make this difficult. Thank you!
