I've just bought a Fenix HP11, which seems very good. I read lots of good reviews. It was £55 direct from Fenix and I am going to get some decent rechargeable batteries for it. so it will be about £75 all in including charger and batteries.
I've yet to use it fishing, but it seems very bright and I like the fact that you don't have to go through all of the settings to get the desired light output, like you do on the cheap crees. It feels very robust and well built too. The lensers look good too, so I guess it is just personal preference really...
