Here's one for 20 if you're interested:

Has LED fuel gauge, which is a good feature, and it's 4000mAh

Its kind of big though.
I suggest getting Li-po's from batteryspace.

That's true. The case is big. However, the actually battery cells only account for about 1/3 of this space. It's really only 4 li-ion cells which are only slightly longer than AA's. The volume therefore is relatively small. However, point taken that Li-polys are smaller overall, but slightly more expensive too.

See pics:
