Best AA Rechargeable Batteries?

[rawfuls]

Well, I ordered a MintyBoost PCB board (http://www.adafruit.com/index.php?ma...aed6d6de6c8580)

What it is, is basically a portable USB charger, that runs off double AA's.

I also ordered the needed components, as I really wanted this to be a DIY project for next weekend (after first set of finals)...

Anyways, instead of the standard 2 AAs it uses, I'll be tossing in 4 AAs.
But looking into rechargeables, since it'll be my charger during school.. and it'll probably be used like cake eaten by a fat kid. Anyways, I'll need some long-lasting (duration or life-time longlasting). Charge time doesn't matter, since I'll probably be pullin them out every day, tossing them into my Bantam BC6, and charging them like that... Daily routine, yipee..

Any suggestions?
I've got these random Panasonic ones, that's leaking battery acid, or did at least, but are still used, just for testing purposes..

I saw some people are loving Eneloop's, but suggest away!

BTW, trying to spend as little as possible, but if something's gonna be expensive, but damn worth it, I'd look into it...

Thanks!
