Rechargeable batteries.

I use AA in various cameras & flash units.My Ansman NiMH 2400 seem to have bitten the dust after a couple of years.
What do YOU use as for rechargeable AA's and are they expensive?

Thank You

I just switched to Eneloop. Affordable, yet great.

I use the IMEDION by Maha. They are similar technology to the Eneloop. These batteries will still have most of the power left in them even after months of storage. This is ideal for photography where you may not use your flash for 3 months but then would like it operational in a moments notice. The older NiMH lost their charge very quickly in storage. The Maha product is available from Canadian internet retailer www.paulsfinest.com . His site also has a great deal on info on batteries and chargers that I found useful. I have purchased several orders from Paulsfinest with good results.

Thanks folks.Great Canadian link rszumski.
