I own an Energizer CHM4FC, which you can get for around $25. It handles
AAA,
AA, C, D, and 9V. There's a NiCd / NiMH switch for cell type. I use it

5400mAh C cells, and it works fine.

The catch is... The maximum charge current is ~ 500mA, and you have no
control over what the charger does.
Get a MAHA PowerEx MH-C9000. It does only AA and AAA cells, * but you
won't
regret it. You can pick the charge rate, and there are functions (such
as
refresh and capacity) not on simple chargers. You can see exactly what's
going on.

The current $52 price seems high (I have two, purchased at around $40
each),
but Thomas occasionally has sales.
* MAHA told me it has no intention of making a C adapter. Rats.
I have that MAHA charger and it can't correctly discharge Sanyo Eneloops
(I think they have a little higher impedance than other cells) and the
charger uses some horrible high current pulse mode.
Then on charge one day it put 3.6Ah into one of my 2Ah cells. I don't
use it anymore.
I've had trouble too with low discharge cells. My charger has two charge
rates at the low rate it may not pick up the drop in cell voltage when
fully charged but they work OK at the higher charge rate
Then again, I have had troubles with the Lacrosse BC-900 type chargers
too. Only they just break after a while, but work Ok in general.
There are also hobby chargers. I have a Thunderpower at work for some
LiPo cells.
