Researching the less-expensive 100 point (Parker's rating) wines on the market in the US:

Here are (IMO) the best choices for the wines rated 100 points by Robert Parker. (I omitted many on his list because they are either much more expensive, or I couldn't find them available on the retail market.)

Old World:

1. 1990 Montrose $500 (at this age, this is a good choice)

2. 2009 Montrose $319 (only 1 bottle left)

3. 2009 Clos Fourtet: $295 (needs 5 years of cellaring, then it keeps for 50 years; this is a good choice)

4. 2009 La Mondotte: $395 (2015-2045)

5. 2009 Leoville Poyferre: $250 (2018-2040--very tempting and a Second Growth)

6. 2009 L'evangile $395:

and the older Bordeaux that I can still find are much spendier:

7. 2000 Lafleur: $1699

8. 2009 Le Pin: $3600

9. 2005 L'Eglise-Clinet: $769

10. 2000 Cheval Blanc: $600

New World:

1. 2005 Quilceda Creek Columbia Valley Cab: $250 K&L (now-2033)

2. 2007 Quilceda Creek Columbia Valley Cab: $275 (2017-2037)

If I went New World, I would get one of the Quil Creek cabs. 

And here are the Napa cabs (ignoring the utterly ridiculous prices):

3. 2005 Colgin Cariad Proprietary Red: $375 (hold until 2015)

4. 2007 Colgin Cariad Prop Red: $500

5. 2002 Dalla Valle Maya: $585

6. 2007 Harlan: $940

7. 2007 Kapcsandy State Lane Cab: $400 (2012-2042)

8. 2008 Kapcsandy State Lane Cab: $400

Finally, there is also a Cayuse '08 Impusivo Tempranillo. Haven't been able to find it yet in the market, though.
