i agree with this, and i own one.
2xAA is the best configuration for a light that takes standard batteries.
edit: if you go with lithium (or even with AAs), make sure you go with rechargeables. the cost of batteries adds up quickly otherwise.
While I prefer AAs, the Coast LED Lenser HD7438CP is a winner. It uses three AAAs and comes with a bright, adjustable beam and an easy-to-use clicky tail switch.
I discovered it at Home Depot for $49 before I found the light here at CPF and got myself a Fenix, Nitecore and a Photon keychain.
It's a dandy, and is definitely worth checking out next time you're at HD.
