Simply, Wize is a product ranking site. Unlike most similar sites, it combines user opinions, expert opinions and 'buzz' into one 'wizerank'. You can browse through a category, and you can filter results to find the particular one you're after.

As well as digital cameras, they also cover lenses, flash units, and a range of other products (but they're not photography related, so who cares?)

Thanks Megan, for sending me this site!
