Should i trade my 8gb ipod touch 4g for an 8gb 2nd and 3rd generation?

I can't make up my mind. Both of them are in great condition. My 4th generation whole left bottom corner is cracked and the home button is janky (its cracked yet you can still touch the screen and all). but theres no camera on the 2 and 3g D: lol whats your opinion?
