I would also take into consideration what you are gonna use it for most of the time. I use mine when Im working out and snowboarding as well as around the house etc. So I went with a Nano. The normal Ipods were too big for me to use comfortably while working out even with an armband, etc. The nano is so small I cant even tell its there. I have the 4gb model and it is perfect for me right now. If I was still traveling alot I would get one of the normal ones though, since I was gone for a month at a time and the larger hd would have been nice. The video ones are definitely out for me, those things are huge and I barely watch TV as it is.
