The HPI battery charger that came with my Baja seems to have given up working.

I need to buy a charger that will charge the Baja and while I'm at it I might as well get a charger that can take care of all my other rechargeables in my nitros and handsets.

I know nothing about electrics so can you guys recommend a charger that is good but not too expensive

Any help would be appreciated

Cheers
