Consumer Reports has done features on this issue, I can't remember when. I buy brand name on sale with coupons. We tried rechargeable eons ago, but frankly, it was an expensive pain in the neck that just didn't work for us. If you are really well organized, and use bucket loads of batteries all the time, it might work for you, but it is really expensive to get on the rechargeable band wagon only to find out it just isn't for you. For basic items, you are probably fine with going with store brand.
