I finally stopped messing around and went with Dinotte - a 200L in front and a 140L in back. Since I had AA rechargables and a charger, so I got them without those. If you check their website early in morning you can probably catch them on sale; these lights have been $105 every morning this week, but only until about 7:30 AM eastern time. (That's $105 each).

It seems like a lot, but these lights are excellently designed for cycling. They put out a lot of light, they have blink modes that have high intensity blinks above low intensity steady so you don't need two lights for that, and they let you know in plenty of time when your batteries are running low, and they have limp home modes where the light is still on but in low mode. Also they're about as close to bulletproof as you can imagine. Plus they're made in the USA and their customer service is outstanding; they'll even upgrade older models of their lights for a reasonable fee.

You can get cheaper lights but eventually you'll spend this much anyway as you try different ones or they break.
