what size memory stick do you guys recommend for 1.5 psp's.

(you know because of all the extra homebrew and hacks i will be puting on it...)

would 1GB be enough because anything after that is way too expensive for me...

I personally have 2gig and i find that it's not enough cause of the big iso but after compressing it, sometimes it's still big like tekken for example. 767 CSO file, imagine the iso file. Look at more places to buy the memory cards and avoid ebay at all cost cause the cards there could be fake.

kool thanks for the info. but if i were not to run iso files (which i dont plan to) then would it be fine?? i mainly want it to run homebrew and emulate 2.71 with dev hook.

Sure, Devhook doesn't take up that much space, and if you use game emulators, you can still fit a lot of retro games on an 1 gig.
