You could spend ages trundling around shops in your local shopping centre or whatever, but the best places to go these days are online. I suggest www.dabs.com, www.ebuyer.com, then finally www.kelkoo.co.uk. On any of these websites they show the different price ranges of cameras, and the ratings are pretty accurate as well. (you can get a top bargain from kelkoo, because it compares all the prices of whatever you want, in this case webcams, and puts them all together in one nice tidy list)
