Getting my music to the new era...

Now that I have a laptop it is time to finally put most of my music in digital form. The craze of iTunes and iPods is so understandable to me now. (iPod will be next purchase) It has to be one of the easiest programs to use. I started this morning at the crack of dawn and have 32 albums imported so far, another 400 to go. I probably will only do a 100 until I get an external hard drive. I already have 2 gigs of music.. (like 398 songs or something) Ok, now 33 albums... How many left now?

Which iPod should I get?
