I've been hoping to pick up a Surefire E2e sometime soon, but the finances don't look like they'll work out until after Christmas...
But, I found something to get me by! At Sportsman's Warehouse today I found a Cyclops CYC-XCF for $34.99 (just marked down from $80). It's a 2-lithium cell 80 Lumen light which is the same length as the E2e but slightly thicker. I'm not convinced it's actually 80 lumens, but hey, it's plenty of light for me. Comes with a holster/pouch too.
Here's a link to the flashlight on the manufacturer's site:
