PS3 is one of the few systems I have ever owned or really ever played.
I want to get one for some ps3 exclusives, but I would like to be able to run home brew software on it.
I know the original fat model is the best one, but I’ll skip that as they are really pricey.
Can someone give advice on whether I should get slim or super slim or anything else to look out for when making the purchase?
No matter which model you get, do replace the internal hard drive with a SATA SSD. Virtually any SSD will do since the bus speed is the limiting factor on PS3
Later revisions of fat models dropped PS2 hardware components and should be cheaper to obtain. Depending on which PS2 games you want to run in addition to PS3, the built-in PS2 emulator can still be good enough on these. There is a game compatibility list somewhere for PS2 emulation on CFW.
