Yes, the NIMH batteries will give you the most for your money. Plus it's best to play it safe since that is what Nintendo says to use. The Rayovac NIMH Hybrid series from what I hear are the best. They may be hard to find in the stores since they just came out. They can be purchased off of Ebay though. I have always used Rayovac rechargeables and feel that they outperform their Duracell and Energizer counterparts.
