I use the Light & Motion Urban 550 and I find that super bright and super convenient. However, I paid only $85 for it last July at Amazon (seller was Clever Training), and now it's going for $100 more, which I would not spend/have spent. Here's the link anyway; it includes a L&M video highlighting the features which I really like and now require.

PS: I still use my "Blackburn blinky" (Flea front and back) the most.
