Maybe its just me... but i would not think spending a extra 30-40 dollars on quality movers would merit me risking them failing on a 2-4 thousand dollar tank.
But thats just me....
I am a firm believer of you pay for what you get... unless its a hobby tax... like a Reef tax because they put the words REEF in front, or Gamer Tax, because it has a bit more LED's and the words GAMER spammed all over it.
I have asked movers, and professionals, and they all say if i want something quality and that they trust and have been using for years, its IMT.
