It seems some of the very popular vendors are still selling the 2007 version of the iPod classic. The specifications are so close to the same you are not likely to notice unless you pay very close attention to specifications such as battery life. However, the original 6th generation iPod Classic had tendency to crash and need resetting. So you definitely do not want to buy it unless you are getting a significant discount from the price of the 6th generation revision 2 iPod Classic.
