Lomo Madness

Okay so this is completely out of the blue, but I'm seriously thinking about getting one of these Lomo cameras.
Not only do they look adorable in all the different shapes, sizes and colours but they produce some pretty amazing photographs.
A couple of my friends, Amal and Michelle have them i think, so i need some help!
Haha, i haven't really gotten around to researching them that much but i was wondering if anyone knew anything and could help me out?

-Roughly how much are these things?
-Are they developed on film or are they digital?
-Is Mooks the only store you can buy them?

So basically if you have any information, don't fret to help my lazy-ass out :) You can just make a comment here or drop by a formspring, on the right column.

These 'Diana' blue cameras look simply adorable, they're almost indescribable!
I don't know whether or not i should get one of these or should i just be patient and wait untill my 18th, which is near year, to get a DSLR as promised by my mama.
It doesn't hurt to have both right...
Maybe i can just have both...
CONFUSION!
