I went with the M1000 because its mouch easier to change batteries after a couple of years when they die *Lol*
The m1000 unit is 3 times wider but the possibility to get a spare battery is kinda important for me.
I discovered that you can fit a Nokia battery in it too, just search for my other threads or take a peek here for my review: www.pspfaq.tk
Hope that the info helps you decide, but i would strongly recommend the Holux M1000 unit instead of the 240 one
Cheers.
