Greetings, fellow forum members.

I'm posting here because I'm thinking about buying a used PSP, mainly for retro emulation on the go. I'm considering the 2000, because the 1000 isn't readily available in my local area, and it seems to be the best combination of features and mod-ability (plus the slimmer profile takes up less space in a suitcase). However, I don't know much about PSP modding, and I have a couple of questions...

NOTE: Please, only answer if you've had hands-on, personal experience with PSP modding and homebrew. Smart-arsed comments are OK, as long as some useful info accompanies them. Thankyouverymuch.

1. Aside from the PSP Phat (1000), which model is best for modding/homebrew?

2. Are Pandora Batteries, Magic Memory Sticks and CFW still necessary, now that homebrew can be "signed" to run as official software?

3. What are the pros and cons of CFW vs. "signing" apps?

Thanks in advance, guys.
