Just wondering if most everyone is using rechargeable aa batteries in thier radios? I'm kinda tired of spending $$ on Energizer's all the time and thought it might be a worth while investment in the long run. I was at Best buy yesterday and noticed a 4 pack of rechargable AA's (don't remember brand) plus a charger for $40.00. I don't know if that's a pretty normal price or if there are better deals or options out there? Let me know what you guys think. Thanks!
