I will put a vote in for the Maratac AAA. I have had no problem at all with the keychain attachment, and its in and out of jeans pockets several times everyday. The finish is getting tarnished but it always turns on. I like the bright setting for when you need it, sometimes its useful to throw extra light at something (to see it clearly or to confuse /blind it).

I ordered it from http://www.endtimesreport.com/survival_shop.html#Flashlights they ship internationally and I have been very happy with the service after two orders from them. I will be getting more for the inlaws for Christmas
