Can anybody recommend a decent HD camcorder with at least 20x optical zoom that has good, artifact free image quality even in low light conditions? Ideally I'd like one with at least 16GB of built in memory, but it's not essential. My price range is under £400 ($600), but I don't mind buying second hand...
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
