I'm looking to buy an MP3 player for my wife for our anniversary. I want to keep it around $100, but may be willing to go to $150. I don't want to spend too much in case she thinks it too complicated and won't use it(it needs to be fairly easy to use). Sandisk seems to have a couple of options that look good. They have a 1Gb that also has an SD slot, or a 2Gb for about $30 more. Are these good options? I also want to buy one that I can buy a car modulator for. What others should I be looking at in the price range?
