I don't know of any all-in-one packages that are bright enough for me, so everything I'm talking about here has a separate battery.

The Dinotte 400L at $229 is above your price range but worth a look I think. It's a lot of light in a respected name.

I used to have their AA version and can't recommend it. The battery system is flaky. The light engine was solid though, and I'd bet that the LiIon version of it would be fine.

Personally I'm a cheapskate and a bit of a DIY'er and am very happy with my Magicshine. I think the new version of their light at about $95 is a great deal, especially if you also get a Y power connector and their taillight. You just need to bear in mind that the cables are susceptible to damage if you pull on the wires to separate them. I found that no matter how careful I was, I wound up pulling on the wires eventually, so I eventually set it up as in the photo below. The plus side is that replacement cables are about $3 for this light, so even if you damage them, so what?
