I've got a Hotshot, and it's definitely nice and durable, but I don't particularly like its extremely focussed beam. I'm thinking about getting a Danger Zone instead.

In the winter when I'm riding at night a lot, I use a Magicshine which is way brighter than any of these and runs off my headlight pack, for $30, but if you have to buy it with the battery pack it's not only huge but way outside the budget.
