Cheap charger for 10440?

I am having trouble finding a charger for 10440 that is safe. It seems that a lot of chargers can phiscally fit that cell in the charger, but the current is too high.

Any suggestions?

is the WF-188 do-able?

I use the WF-188 for my 10440 cells. Because of their low capacity (300mAh) the 250mA charging rate is optimal.
