I have checked this seller on ebay and people are claiming they bid on a 4GB and only get a 1GB. I didnt see the seller offering gigabyte(GB) players. Everything is offered in Gb(gigabit). It seems like the going price for a 4Gb player is around $50. Thats a sweet deal considering 1GB ipod nanos are going for $100. Also if you actually do the conversion 4 gigabit=512 megabytes. I think people are getting more then advertised. Just thought i would throw my .02 in
Here is the information i found on the web about gigabit
