How big? and how much do you want to spend?
If you want something pocket-sized, then i'd strongly recommend Sony's W series, i've owned the WX1 and the WX7. Amazing cameras, quick turn on, quick focus, quality is outstanding for its size, 10.odd megapixel and full HD video - they have the exmor sensor too making the performance in low light levels really good. Everything you shoot has a gentle purple filter over it too. The WX100 is out now, its around 150 pound but worth every penny.
If you're looking for something higher level, but still small, then the best advanced compact i recommend is the FugiFilm X10. I have one myself (after a lot of research into them and other similar cameras) pound for pound value they can't be beaten. If i'm honest, i was a little let down by the picture quality, but the video quality is really good and its a very robust little camera. they're around 260/280 brand new i think - but i picked mine up ex-display for 210. So just keep your eye out.
If you want something better again, then the best bridge i've ever used is the Sony NX-5r. I've never been a fan of bridge cameras until i used this, its such a nice camera to use and does everything a DSLR does but half the size. you don't get the view finder and the range of lenses are limited, but for what it is, you can't really go wrong. A new NX-5r will set you back around 300ish, but you'll probably need a lens on top of that too since the kit lens isn't too great. so i'd budget for 400ish.
hope that was useful
