this isnt a quote or anything, but i think someone on here ordered some. the first set they ordered, the motor got too hot and melted(in the tank, but he caught it just in time) the second or shall we say replacements, something happend and nuked his tank?? there was a thread started i think.
my honest opinion, just look at the for sale portion of RC. they sell Koralia 3's and 4's for 15-30 bucks for the real thing. in fact, eairly i think someone was selling 2 for 30bucks plus shipping.
