need help with charger

[mk351e]

gents, I'm on to picking out a charger now, and BIG surprise, I'm stuck again! So, based on what I've read, everyone loves hyperion, AND they're supposed to be easy to use. So, sounds like they're for me! But which one? I need something easy to use, has a built in balancer, and I've got a strong preference for the ac/dc model, as I don't really want to have a seperate PS. I'm willing to go there if it is worth it. I'm going to be charging a 6S1P 5000mah Zippy, possibly the occasional random NiCd or NiMh, and most likely a 4S1P 5000 mah Zippy as well. I don't want to charge too fast, because if I understand what I've read, I'll kill the lifespan of my packs; but I don't really want to sit all day waiting either. If I can SAFELY charge the 6S in an hour, that would be good I guess. The reason I'm asking about this is that this charger is only 50W, vs. 250W for the next model up. Not sure what it means exactly, but I know someone here does!

Also, I really can't see ever charging a pack bigger than the 6S 5000 pack. I may wind up with 2 of them, but I just can't imagine having a larger pack (after playing with numbers on BrianG's sheet!).
