PSP worth buying?

[mushussu]

Hi ,
Living at the bottom of the world here in tasmania I cant get hold of a PSP through a local store till september 1 (If I Basically pay for it now).
Yeah I could order online, ebay, etc . But warranty support (especically with a sony product) is lacking , EB games over here is great for returns so I`ll be going there (one of my kids(4year old) dropped a gba (3 day old)in the toilet , I told the truth and they still replaced.

Anyway back to topic.

Are they worth it.? $400au about games about $70
Do they Break? (can kids)
Any stand out games?
Any emulators on the way for say ps1 game backups?
Prolly not a good question but I heard something about mame psp? would there be any legal stuff if there is a version?
