Wines for keeping.

[Locuraman]

I am inexperienced in choosing wine. I once read a book which gave great advice, drink what you like and don't worry about what the experts say. I have followed it but now fined myself in a dilemma. I am now in a position where I can buy about $50.00 worth of wines a month. I know some wines get better with age and would like to buy some inexpensive ones to keep for 5,10, or 20 years. The question is, how can I find wines that will keep and hopefully taste better after time? A not so local wine store recommended a 1997 Bordeaux, Chateau Landereau. I bought some but don't really know how it will turn out. Is there any where I can go to fined out about finding good, inexpensive "keepers"?
