Which to get Vortech pump MP20 or Tunze ?

[robert J]

Is anyone here using a Marine Vortech pump MP20 ? Is it a good pump or is it not worth to buy ? I am thinking to get this pump instead of getting Tunze, but when I watch on Youtube video, the waves in the tank look similar to the wavebox. But the wavebox is much more expensive than this pump. I don't know should I get Tunze, or Vortech pump, or nano wavebox ? My wife loves to keep sps corals only, any suggestions which one I should get for her to make her corals happy.
