CR123A Batteries

[alamo5000]

I have several lights now that all use CR123A batteries. Honestly the hand held variety gets used quite a bit and hence I burn through batteries.
Up until now I have used solely SureFire branded batteries.

What I am wondering is if anyone has tried out or tested any of the various other options available on say Amazon? There are some that are substantially cheaper than the SF branded ones...as well as some that are much more expensive.

If you have ever tried out other brands, generally what has been your experience?

Edit:

Bonus points if you can give info on rechargeable 123A batteries. From what I hear they can be used, but they are not very good in that application.
