For a good charger you could try one of these:

At only 36 minutes for up to four 2100mAh NiMh AAs, the U-Smart claims to be the worlds fastest charger. It's available (inc 4 x 2100mAh) for £35.42 + vat from
CPC.
For some non-rechargables you could try these:

At 2900mAh, they claim to be the worlds longest lasting AAs. They work well in the cold - ideal for trips to the Himalayas
- and they have a very long shelf life so they're ideal as a backup set. Expensive mind, at about £5 a pair!
