How about a SkyRay King (or FandyFire UV-S5 version). 4 parallel 18650's are safer than Li-Ions in series. Tremendous flood output. Most lumens per dollar you can get on a budget I believe. At FastTech use coupon code "BLF" for another 5% off. Review here.
Personally I am thinking either a King and/or the Trustfire TR-J12 (5xXM-L) running on 4 C NiMh cells. Not sure which to get first.
