As seems to be the case with lots of Freetrionics stuff, it seems relatively expensive. I already have a cheaper one on order from China ( something like http://www.ebay.co.uk/itm/LiPo-Charger-Basic-Mini-USB-Battery-Charger-module-/220966997668?pt=LH_DefaultDomain_0&hash=item3372a8cea4 )
Charging these cells is pretty complex, you are recommended to use a different charging current depending on the capacity of the battery for example, so it might be that the Freetronics one does a better (or at last more configurable) job
