I use the apache 2030, which i believe is an excellent value. I got it on sale for 30 bucks form hobby-lobby and it can charge 1-8 cell nicds/nimhs (A standard receiver pack has only 4 cells), and 1-3 cell lipos. I think its a great starter charger for the hobby. It certainly kept me on the field for a longer time!

Good luck
