In your budget, I'd recommend looking at itp's latest 2xCR123 offering as well as some of the Romisen ones. You can use RCR123s in most of these lights which will boost the brightness a bit.
Note that 1 CR123 will not give enough runtime for your needs. Make sure to go with 2xCR123 or at least 1 18650. You also want a light that is pretty floody; you don't want a searing intense bright spot while you are trying to work.
If there was a decent BIG flood to throw option, I'd say go that route. But they are limited to CR123 or 1xAA.
I'd like to point you to the itp A6 Polestar. It uses 6 AAs, and you can use Eneloops for rechargable goodness. You have lots of battery life, it is floody, reasonably sized, and has 3 good brightness levels. It is 80 bucks though (minus any discount, plus batteries). I have one and it is great. If you really need a decent quality light, I would recommend you spring for it. (at goinggear, you can get it 10% off and free shipping).
You can get a pack of 8 AA, 2AAA eneloops with a charger for 30 bucks on Amazon with free shipping. Just a charger alone if you don't have one will cost 15-20 bucks, so this is a nice deal. Charger seems to work well based on my tests.
One final option is a P7 using 1x18650 from Deal Extreme. However, they are hit or miss, and shipping takes a while. Still, for 32 bucks you can get a multi-brightness mode light up to 300 real lumens (they claim 900 typically for the P7). They are floody and a good size. Runtime on medium is good (which you would likely use most of the time). The catch is that you have to buy a charger and specialty batteries that arent much good for anything else. A 2x18650 light costs almost double!
