GoPro Type Camera for 10 Year Old

[Beascheerfulasyoucan]

Does anyone who knows anything about cameras have any suggestions about a GoPro type camera suitable for a 10 year old? My DS loves filming little videos but I don't want to spend GoPro prices yet.
Feeling totally clueless!

I bought one from Amazon it was called a Splash it was very good for the price. Came with waterproof casing and all sorts of different attachments to put it on helmets, bikes etc. Very sturdy survived some harsh treatment. Unfortunately didn't survive being run over by a lorry.

Thanks, that's really helpful. I'll take a look at it. And try avoid lorries...
