There's a plethora of very tasty and very inexpensive Argentine Malbec on store shelves right now. Seems like you can grab just about any bottle you see and you'll take home a winner! Another fairly inexpensive Malbec out there is the Alamos 2011, which you should be able to find for $12 or less.
This went really well with a roast pork I recently prepared with some butternut squash and green beans. A simple meal, but the wine brought a delicious elegance to the table with some sturdy tannins on the finish. Like many Malbecs, it was dark, inky; the nose a delicate mixture of floral and fruit scents with a racy flavor of blackberry. This is definitely a good find, but I think for the price and the taste I might lean more toward the Diseño I recently wrote about.
I rate this with an 8 using my scale at the left.
