If you aren't going to install to the HDD, then probably the 60GB, unless you are super crazy rich and can afford all the DLC for every game you buy (a la $110 Fallout 3)
I would definitely go for the 120GB. I got an Elite back in February and what with all the new arcade games coming out and all the DLC for GTA IV and the like I have used up 50GB already!

60GB or 120GB mmmmm.... I have a 120GB but i'll soon sell that once i get my 250GB and use a new transfer cable to transfer all my save data from my 120GB to the 250GB.
