There's plenty of gaming bundles around with various sizes of hard drive. If that's all you want to play the i suggest getting a PS3 with the small HDD. You can always upgrade your HDD at a later time and we have various threads on how to do it. As semipro said above i too wouldn't be surprised if there wasn't a dust bundle that come out.
Don't be too hard on the controller side of things. It's really not that bad once you get used to it.
Funnily enough i'm looking to go the other way and get back into PC gaming. I've been lounging around with a controller for about 4 years now so going back to sitting at a desk with a keyboard and mouse is going to take some time to get used to.
