Even if you don't like the Phillips for whatever reason, Cygolite makes a series of ExpiliOn lights that all have a self contained battery that while it is a proprietary battery they are user replaceable and you can buy more bats and swap batteries all you want. On Amazon their EpiliOn 800 is now only $107, but Amazon has a whole series of them; see: http://www.amazon.com/s/ref=nb_sb_ss...yg%2Caps%2C334 just pick out the one you can afford.
