I get CR123A batteries for well under $1 ea shipped. I'm too cheap to buy rechargeables! Over time they'd be worth is but between the high cost of the batteries and the charger it's not worth it to me...I don't go through batteries fast enough to make it worth buying all the stuff to use rechargables.
