Here's a few ideas for you for QPR Bordeaux wines. In the Left Bank, look for:
Grand Puy Lacoste, Lafon Rochet, Le Crock, Branaire Ducru, Gloria, Malescot St, Exupery, La Lagune, Cantemerle, Haut Bergey, Poujeaux, Senejac, Branas Grand Poujeaux, Cambon le Pelouse, Tronquoy-Lalande, Deyrem Valentin, Charmail and Malartic Lagraviere.
Those are are really great examples of value Bordeaux wines from the Left Bank. There are more, but that's a good place to start. You can read details on any or all o those wines on this site. Use the article search box.
I think you can even buy wines with bottle age from most or all of these producers for under $100 and recent vintages of course range from less to a lot less! Do you know these wines?
I can also put together a list of wines for less money from the Right Bank too. Want some tips from there as well?
