Ipod touch choice

Ok so right now after my birthday i have alot of money and i wanna save up to buy a new ipod touch since my first one got stolen sometime last april and i really did miss the joy of listening to my music in class, in the car or where ever. But the thing is idk if i should get the 4th generation ipod or the 3rd generation because i feel as though the 4th will be easily damaged and it's pretty expensive but the 3rd one is cheap but doesnt hv as much options as the 4th so im actually lost on this one. little help would be pretty good!
