Really depends on where you buy it. Usually $7-10 each in the retail stores. Battery dealers on ebay is much cheaper. You also have to remember...these batteries last 3-4 times longer than AA or AAA.
You know.....it would be a toss-up, because they both rate out about the same. However, if you tied me to a stake, poured honey over me, and turned the red ants loose....well, I'd have to choose the Minolta. It has a bit more advanced functions. Not much....but a bit more. Of course, that's my feeble opinion, and, if you put that with a buck...you might be able to buy a cup of coffee. Ok, Ok.....half of a cup.
