Inside a cheapo NiMh charger with schematic.

I bought this to see just how much of a charger you get for a mere £5. It turns out that it's actually quite nice inside and has good slow-charger (200mA) functionality.
It has a cut-off timer that may be as short as just 10 hours so it's probably best suited to cells under 2000mAh or for topping up larger cells. That timer section can be bypassed internally though.
