Last year I bought a Canon Sureshot Supreme for £3 from a charity shop. The little camera has a razor sharp lens and is a handy go anywhere compact.
I have had very good luck with Canon Sureshots as well. Very sharp for a $3 point and shoot. I got one when I was in high school, and I still have it. Now that I do "real" shooting, I was going to give it to a friend, but found a similar one in a thrift shop for $3. They are great $3 cameras, and I am glad to not be giving mine away after all!
