Sure, they are called Jebao's. They don't last nearly as long and are nowhere near the quality of the Tunze's. You need to clean them very regularly because the motors are weak and don't tolerate much if any buildup in the magnet cavity. They are also prone to power supply failures. The Tunze's on the other hand will take a beating for many many years even if you don't maintain them very well if at all. They Tunze's have much better power supplies and much better motor blocks and impellers.
