The X1 isn't very popular on CPF because it's somewhat heavy for a 1AA light, and its beam is very narrow due to the focusing optic. Generally, low powered lights are best for close distances and you want a wide beam with lots of spill. The X5 is more popular (5-led flood powered by two CR123's) and is on sale right now at Countycomm. I don't have either one myself.

The version that everyone on CPF wants is the Ultra-G, which is the government version of the CMG Ultra and is hard anodized. They were available brand new for $14.50 or so until early this year if I remember right. Used ones now show up on sale on CPF BST fairly regularly in the $20-25 range and quickly get snapped up at that price.

There is also the Peak Kilimanjaro which is a nice light but is around $40 in the ultra power version. And as mentioned, the Arc AA is supposedly coming back.
