Hydor 240 vs. SW2 Jebao

[Gatling]

Title is self explanatory. I have a fluval 13.5 and I need a wave maker/power head. I am willing to pay the $80 for the SW2 but I heard that the power of the wave maker dies down after 6 months or so. What is a good, long lasting wavemaker/powerhead?

You could look at the Nero 5. I bit more pricey though, but what you are looking for.
