I'm looking for a slimline PS3 console on eBay, DH's birthday in a couple of weeks, but I'm a bit confused by all the different models. The cheapest I can find is £135 for a second hand 120gb console, which ends in 90 minutes, but there seems to be ones up to 320gb available. What does this mean? DH is not a serious gamer he maybe spends a couple of hours a week playing GTA or snooker so will the smaller one do the job just fine?
