If you don't already have a PS3, the best solution to this problem is to just buy a used one. There are a lot of good used PS3 models out there with the PS3 Slim being probably the best one of the lot. It's significantly smaller than the PS3 "fat" (original PS3) but has all the capabilities as its larger and older sibling.
PS3 Slim on the other hand is limited to just the console, a thin 'n' floppy manual, power and USB cables and - horror of horrors - a composite video cable and SCART adaptor. Yup, the exact same
Depending on where you live, a late model Xbox 360 might be a better value based on price and availability of games. In the same vein, a fat Xbox one is also kickass value when cheap, as they have a strong backwards compatibility list. A late model slim, or a super slim playstation 3 is still a great option.
