I am thinking of buying a THUNDER POWER RC QUAD 4 X 100W AC/DC CHARGER (TP4X610HV).  At 30% off it comes to around $114.  At this price is it a good choice.  I like the fact it will charge 4 at once.  Any experience, good or bad with this one?

I have a very similar charger that does 4x80w, and i love it. If you have other batteries to charge, you can still charge everything at one time,  which is quite convenient.
I almost bought the same charger you mentioned above,  but mine works fine so i figured I'd save the $$ this time.
