Looking for a used lipo charger
 

I'm looking for a decent used lipo charger I may be able to get fairly cheap. Hoping someone has one that wouldn't meet all their demands or something and they upgraded to another charger for some reason. Looking for something to charge up to 3s lipo and nimh batteries. Pm me if you have something, thanks! Also looking for a stock traxxas 7-cell nimh battery to run in my slash.
