I am interested in getting one PSP. I got noob questions here,

1. is it hard to get the 1.50 firmware PSP nowadays, do the v1.50 PSP more expensive in 2nd hand market?

2. when upgrade to V3.52, can it be downgraded to 1.50? If not, how to run homebrew on 3.50?

3. V3.52 M33 firmware, is it 2 firmwares combine? How to switch from one firmware to another?

4. I think some later games wont support V1.50 anymore, am I right? But then if have to use 3.50, then we wont able to run home brew is it?

5. Can we load games from MSPD itself?

6. How much is one spare battery for PSP (the big one, not slim edition)

7. How is the audio quality when listening to mp3 and wma song? Can we use homebrew software to listen mp3?

added 8. Can we play .avi xvid/divx directly without conversion on PSP? The resolution let say 640*480, do we need to resize to be playable on PSP?

added 9. What so special about PSP slim, apart from longer batt life and smaller?

its my question thus far, this is my first time into PSP since I want a portable entertainment device aside from PC

whats the difference in 3.52-M33-4 and 3.52-M33 ?
And from the 1st post, if I have 3.40OE-A, can I run homebrew ?

is 3.40OE-A a good firmware?

the PSP Slim when use with the slimmer batt 1200mA, the playing life will still be longer than the larger 1800mA on a Fat PSP right?
