Handy if you want a vodem etc. iirc both models can be unlocked too if you look online.
Also the option of Vodafone K4201 Vodem + Prepay SIM Card $10 which typically comes with 1GB free(not stated on the HN page so at your own risk).
Purchase $25 or more worth of items to use the WELCOME5 $5 off code.
Good deal, even better than this. :)
