If battery life is important to you, the Cowon J3 would also be great. It's ranked #1 portable music player here on Head-Fi. It plays almost any lossy or lossless audio format you throw at it, like FLAC. It sports a 64-hour maximum battery life when playing music, and 11 hours when playing video. It comes with built-in speakers and a 3.3" AMOLED screen. It also supports Bluetooth communication and comes with FM radio and voice/radio recording. It comes with 8GB built-in storage for music, but there are also 16GB and 32GB models. If you need more space, you can expand it with microSD cards as it has a slot for them. If you only need around 20GB your best value would be to get a 16GB or 32GB microSD card along with the 8GB Cowon J3.
You can get the Cowon J3 8GB version on Amazon or B&H Photo Video for $180 (usd)
and you can get a 16GB microSD card on Amazon for $8 (usd)
or a 32GB microSD card on Amazon for $18 (usd)
You can get the Cowon J3 16GB version on Amazon for $220 (usd)
You can get the Cowon J3 32GB version on Amazon for $280 (usd)
You're best route would be to buy from amazon or B&H and they can ship to your address no matter where you are, they are also the cheapest.
If you don't want to spend as much on the Cowon, my next choice would have to be a SanDisk. Those things are an insane value for their price. They don't have many of the features that the Cowon does, and they also have a shorter battery life, but If you get one you won't be disappointed. You also have a MUCH better chance of locating them at local/retail outlets. The Clip+ is a good one, but they also make the Fuze and the newly released Clip Zip. One of those three might have a better battery life than the others, but I don't know which one it would be.
