If money/heat is not an issue, then you should get eheim 1250.
I myself have a maxijet 1200. Cheap, works great, cant complain. The reliability issues with maxijet can be fixed through a simple, inexpensive step. (check forum) And will last just as long if taken care of. Easy to use 1/2 tubing with mj1200 also.
Only MINOR problem I have with the mj1200 is that it vibrates a little (I fixed it by putting a soft rubber eraser underneath it) and to my surprise, does generate some heat. But I'm running inline so no biggie.
I also had doubts, and thought of going with eheim, but why spend TRIPLE the money for a pump of similar performance? Mind you, maxijets are also a LOT smaller than eheim, for those concerned with space.
Good luck.
