Hello all, here are a few more single AA lights that will cost you less than a coffee and donut-- or less than a tea and scone. ;) Again, I haven't purchased these (yet) and I don't know much about the retailer....
SmallSun ZY-C575
$3.38

As usual, I like this simple design with knurling on a large percentage of the body. And I like pocket clips on lights. That is quite a nice looking clip for such a cheap light. The pictures indicate that it disassembles at the head and the tail. And it appears that the tailcap on the disassembled picture is flush to the ground, so it might be tailstandable, although the switch boot protrusion is highly variable even with $15 lights. It is probably a floody light, similar to the MXDL T51 that several of us here have recently bought.
SmallSun ZY-572
$3.11

This one supposedly has a glass lens, which I highly doubt, especially since another cheap Popbuying light features a "Toughened synthetic glass lens". We all know what that means. But who can complain for the price. This one is unique because it has a side-facing wart switch. I personally don't like it much for the switch, reminds me too much of the junky old monstrosities that were incandescent plastic-body flashlights of old.
Additionally, I found everyone's favorite "Powerlight HX-G011" for $2.99 at Popbuying, hopefully it's from the same supplier that DealExtreme uses. They have a ton of colors. Here are the only two colors that are worthy of adorning a flashlight:
