If this is not the place to post I apologize in advance.

Im trying my best to rekindle some gaming love and the ps vita has really caught my eye. From what I can tell, its a portable ps4 that I can even play ps4 on. But as any new consumer I have a few questions that I feel like only daily users would be able to answer.

Ill try my best to not sound too slow with my questions;

1. Fat model or slim model? in terms of the whole oled vs non oled thing, I have an oled iPhone and my last wasn't and I haven't noticed a difference so it doesn't really matter to me. Just looking for whatever the fan favorite is.

2. There's a few game series' from my childhood which I love, and from what ive seen there seems to be some of those on the ps vita marketplace? but the ones im really curious about, if its even possible to get them on a ps vita, are: The Jak & Daxter series, Ratchet & Clank series, and the Spyro Series.

3. Where's the best place to buy one at a good price? I got a $75 amazon gift card from a family member recently so amazon would be ideal. but if theres a good private seller for used ones or something close that would be awesome if I could be directed.

Thanks a ton friends <3
