Ipods? Do You have One?

Do you have an Ipod? I have been thinking about buying one for awhile, but I just can't figure out which kind to get. I think I have looked a a dozen different ipods so far. Is there one that is better than another? Which ipod is the best price? Do they come in colors? Red being my favorite color I would really like a red one. Do they all work the same or are there differences? If anyone has a suggestion let me know.
