What do you recommend?

What should i do,
Easy installer for 3.02 OE-A (can someone give me a link for this please?)
or the step by step one found here http://boardsus.playstation.com/playstation/board/message?board.id=psp&thread.id=2717632
im doing it today and i just found out about the tutorial in the link.
The guy who wrote the tutorial said that the Easy installer is more dangerous, but i would like some second opinions

dude, i did the easy installer, and although it didn't work first time, it never bricked my psp, and its all done im now OE-B.
I'l help you out, like Mailas G helped me, or he can help, either way, both of us used the easy installer and as long as you dont mess with it whilst its performing the upgrade, it should be fine!

EDIT: here's the easy installer link - http://www.pspbrew.com/?page=fileInfo&cid=5296&d=3352

Just use the installer (.exe version) with your PSP connected and it will convert all the neccesary files.
I had a clear memory stick for this, just to be safe and when its all in place, run the upgrade from the psp.
(if you're 1.50 this is the best choice anyway)
