I've got the Integy 16x4 Charger. While the specs are very impressive for the price, I've lost confidence with it on smaller battery packs. It seems to false peak very often. Other chargers, like the cheap Duratrax Piranha allow you to adjust the threshold voltage which reduces false peaks on slower charging small battery packs. The Integy has no such adjustment.
I just picked up the Triton which is on sale at TowerHobbies. It has all the features of the Integy, plus can charge LiIon and LeadAcid. It does require the purchase of a power supply.
