reasonably priced bordeaux to drink now?

[little tanuki]

Hi all. Great board you have here!
I've been trying to educate myself about wine....bought several books, including the Wine Bible and have been having my own private little tastings at home. [img]http://wines.com/ubb2/wink.gif[/img]

Probably like all beginners, Bordeaux scares me. [img]http://wines.com/ubb2/smile.gif[/img] I have a basic understanding of the meaning of the various crus and can recognize the different regions.

What I need help with right now is selecting several wines from different regions and chateaux that won't bust my budget but will help me gain a better understanding of Bordeaux.

Can anyone suggest some wines from Medoc, Pomerol and St. Emilion between $20 and $30 that are available at a reputable wine shop?

Thanks in advance!
