A bit more than your $80, but I feel compelled once again to reccomend the Fire~Fly III. $136 including shipping, 1 battery, and charger. Don't tell DSpeck, but for what you get, this light is a bargin. You can set it up for 2 or 3 levels, and set the brightness levels to what you want (low/high/burst). It's a masterpiece in metal, and a joy to operate. Plus the fact that it uses rechargable batteries means that you'll use it more since it's free to operate, and in the long run might cost less than a seemingly-cheaper light that can't use rechargables.
The other option I can see is the Fenix L1T which you can feed with NiMH rechargables. It's not confirmed yet (at least that I'm aware of, and even if it's not, it's an inevitability) but the aftermarket bodies (available
here) should work with it, and you can feed it with 123A 3V lithium primaries and even 3.7V lithium ions for a brighter high level. I don't know yet if a 14500 will fit in the L1T without modification, but if it does, that's another great option (without having to buy the aftermarket body).
Beyond those 2, there isn't much in the way of inexpensive 2-stage lights, at least 123A or AA based ones. The Jetbeam Jet-1 2 stage isn't available yet (nor yet, I don't think, is the commercial release of the Jet-1 anyway). There's plenty of single stage ones that are nice though. Peak has several (the Caribbean is particularily nice), there's the very-soon-to-be-available Fenix P1, the Amilite Neo T3, and others.
