There are many good suggestions in this thread. Particularly, the idea of considering what sort of camping you do, and thus what sort of lights you require, then buying lights (plural - redundancy and suitability to task) to suit your needs.
1/ Any modern high-output throw-oriented light, possibly with a tint suited to outdoor use - TK20, TK11, Solarforce L2 with the new 3-mode low voltage dropin, a 2D or 3D new Maglite
with the Rebel LED (goes on sale @ Canadian Tire), Dorcy 200 lumen rechargeable (if you've got a vehicle to charge from - available from Rona), Quark neutral AA running on a 14500 Li-Ion (covers very low to high output) etc.
(You could just buy a Fenix LD20 body to use with your LD10, if all you need is a bit more output. The LD10/20 isn't delicate, but the TK series are much tougher. The Energizer 2500 mAh batteries are not considered to be good, and *may* be contributing to your concerns.)
2/ One or two low output/floodier lights, either a headlamp or AAA/AA light with clip that can be used on a hat - Fenix E01, LD01, or the three mode ITP A3 EOS (has a true low as well as moderately high output), Zebralight, PT EOS Rebel headlamp, etc.
3/ Area lantern when group/car camping - Rayovac Sportsman Extreme 300 lumen lantern (Available @ Rona - it's too big to carry when traveling light).
Also consider how long you go camping and what sort of batteries you prefer... AA & AAA lights mean you can get batteries anywhere, anytime if you run short.
Sanyo Eneloops are excellent rechargeables in AA & AAA and Shopper's Drug Mart periodically puts them on sale in the white-topped Duracell version @ $7.00 for four. There is an acceptable Duracell slow charger that terminates well that also goes on sale @7.00 with two batteries, although it's most often packaged with the less-desirable black-topped non-Eneloop Duracell LSD batteries. Canadian Tire sells the very well regarded Duracell Mobile Charger (check for white topped batteries if you can find them) and it periodically is on sale too (which is good because the charger is overpriced locally). There is a lot of info here about these batteries.
The lights that run from 18650 Li-ion batteries are often excellent performers - the question is will you have enough charged batteries to cover the time required? Using only enough light for the task at hand helps to preserve both batteries and night vision. Of course, you may want to light up the night at times for entertainment or safety reasons too!
AW sells excellent protected 18650s in the marketplace. His batteries are also available through many good on-line retailers. If you look at the Solarforce L2, you could get a Solarforce charger and batteries with it. There's even a lantern attachment for the L2, which is kind of neat, but not cheap.
I've got everything I've mentioned except the Solarforce batteries and charger, and my suggestion is to start out conservatively. Stick with AA & AAA formats for now, and after reading CPF for a few months, you'll be lusting after lots of high-powered lights, but you'll have a much better idea of what differentiates the different lights.
Read Woods Walker's posts about real-world use of lights in the woods. I concur with his suggested TK20 (the tint is important as well as output) and PT Rebel EOS headlamp. I'd add an ITP A3 EOS three-mode AAA light. That should cover it for now, and respect your budget. The alternative is to go for a higher output light and use it in combination with your E01. Don't forget to factor in the cost of batteries and a charger if needed.
If you still want lots more light then it'll mean considering some of the very high output lights like the new ITP A6 Polestar or other (more expensive) quad-die lights.
