I recommend HD 5850. They are cheap and relatively powerful.

Here's a comparison chart for most cpu's, graphics cards, asic's and fpga's for Bitcoin mining:

And here's one for Litecoin:

Should I mine Litecoin or Bitcoin?
Right now I get 200 KH/sec mining Litecoin and 200 MH/sec mining Bitcoins

Well, Litecoin. No doubt.
There is absolutely no point in mining Bitcoin with GPU's anymore. The electricity bill will be higher than your gain.

If you check comparison sites like Dustcoin ( http://dustcoin.com ) you'll see that Litecoin is currently 75% more profitable right now.
