Hi Everyone, I would like to purchase my first PS Vita and I am wondering which version should I choose: the launch model PCH-1000 with the OLED screen or the newer PCH-2000 SLIM edition. I would like to use it for mainly homebrew applications and retro game emulators and for some of my old PSP backups. Which one would you recommend and why? Unfortunately it is impossible (or expensive) to purchase non-second hand Vita's this time so I am forced to purchase it second hand from a trusted reseller (like CEX in the UK). What are the key point to take care of when I would like to purchase one? What are the typical issues with the Vitas? Thank you for every help and information.
