Why is there any doubt? If you dont wanna wait for the new video Ipod recently announced with brighter screen and 50% more battery life during video playback - you can opt for the exisitng Ipod 5th generation 30GB Video. Costs max 15k. You can get it from jjmehta and enjoy the 1 year warranty on the same.
Personally, I do not like the idea of higher capacity flash based nanos. They are small, slim, in and ofcourse you can flaunt them but honestly an 8GB Nano costs the same as the video Ipod. 8GB/30GB which would you choose? If I would have to go in for a nano, the basic one should do fine.
