hello henry, if you can let us know what price/budget range you are looking at, and what you will be using it for, we can then help to zoom in to some specific models. 
in simplest form, take note that a regulated flashlight will run at the same brightness regardless of whether you are using primaries AA or rechargeable AA. if you are interested to know more about regulated vs non-regulated vs hybrid, you can read more at The Welcome Mat - a FAQ from www.candlepowerforums.com.

for mid to higher end model, i suggest that you pay a visit to GadgetWorld2U's shop at SS15, Subang Jaya. here's a link to one of their sales thread [GadgetWorld2U] on Fenix. They carry a pretty good selection of LED flashlights. 

for entry-level model, you can visit ACE hardware or Jusco's sports/camping equipment section (i believe the consignor has a retail outlet in Garden/Pavilion) at Mid-Valley for some Mini MagLite LED or Pelican or Streamlight. Note that as of last week, price of MagLite at Ace is still lower than Jusco's 

hope this helps...
