At one point in time the only PS3 I had was a 12 GB. My original PS3 had broke, and I didn't fix or replace it until I needed to. The day Dark Souls 2 came out was the day I decided to remedy the situation, and I did so by opting into the cheapest SKU I could find, and it was a 12 GB Super Slim, which I think was around $200 at the time, plus the cost of the Dark Souls 2 game.
I really regret that purchase. The 12 GB limit sucks, but even worse than that is the fact that the damn thing started crapping out on me after less than a year. The system still works, but every so often the fan within the system will become extremely loud... and I mean LOUD... Something is loose and it's probably a simple fix but I haven't bothered to acquire the tools to do so. (Since then I bought a co-workers PS3 for $50 along with controllers and a dozen or so games a couple years ago).
Wow, that sounds terrible. I originally wanted a launch model PS3 with the PS2 compatibility but I heard of unreliability issues along with the super small HDD made me get the Slim model. It's been with me for 8 years and I haven't had a single problem with it.
I don't trust those Super Slim models. Though they do offer bigger HDDs than the Slims, I remember lending my disc copy of Bayonetta to a friend who had a Super Slim. He said it didn't work. I was so shocked, I thought maybe the disc got scratched without me noticing or he did something to it but when I tested it on my PS3 it worked fine. I don't know if that's a common problem or a 1 in a million thing but ever since then, I've decided to take good care of my Slim model.
Anyway, sorry for the old gen tangent lol.
