Your photos might not look as nice if you take them yourself instead of using a professional, but if that doesn't matter then it's worth trying if it'll mean you can save some money.
For under £100 you won't be able to get an amateur photographers DSLR, I think the cheapest one is the
Fuji FinePix at £120.
So that means you'll want a compact camera, with a good optical zoom, flash and other nice features. You'll also need to decide whether you want a camera that uses AA batteries or has a rechargeable Li-ion battery. My old camera takes AA batteries and I think over the years I've binned a few hundred. Such a waste, but I couldnt afford a li-on battery camera at the time.
I wouldn't like to recommend a camera, just incase you went and bought it and it turned out to be a bad investment. So go on to sites like Amazon and check the features and read the reviews. It also might help going down to some camera shops and taking a closer look before buying online.
As well as reviews
this site has many galleries with example photographs of quite a few camera models. If the one you're after isn't llisted, just use Google or head over to Flickr. It's worth seeing the quality of the pictures before spending any money.
I've heard good things about
Sony Cyber-shot cameras and
Canon Powershot cameras (this one uses batteries)
I hope I've been some help.
