Should I buy a PS Vita, or a PSP? Thinking about getting another retro console and I'm not sure which one to get.
You can get a mint condition Japanese PSP-1000 for about a quarter of the price of a Vita! If you solder in a 5000-6000 mah battery you can get some 14+ hours of gameplay between charges! You can also fit a ton of games on a cheap 64-128gb microsd with a $3 adapter, and adding a USB-C port so it charges with the same cable as everything else is pretty easy!
