Some more for the list:
My current favs under $20 (based on Philippine pesos)
Ruffino Orvieto '04 -clean crisp and refreshing, goes with a lot of seafood and asian dishes, or just on its own
Nobilo Pinot Noir '01 -fantastic New Zealand Pinot that I always enjoy with cold cuts pre-dinner!
Trapiche Pinot Noir '04 -easy drinking Pinot from Argentina chock full of berry flavors
These go for what would be under $20 (in the Philippines) I think they may be even cheaper in the US?
