I posted in another thread that I bought a Sporti 6 a couple of weeks ago for 20p ($0.40). I think I was overcharged! It produced images which were sharp on one side but blurred out of focus on the other side. I think it will become a pin hole camera soon.
I liked the portability of it though so I started looking for another one but I ended up buying a Balda Baldixette which is fairly similar. It has a collapsing lens too which makes it even more portable.
