Jebao cant beat the value for money and they are powerful.
I was using the Jebao WP-25 and I thought it did a great job for the money. I now switched to the new(ish) Jebao RW-8 and I like it even better. The RW-8 looks and seems to act more like the vortech. (I don't have a vortech so I can't really compare). Great flow. Wide flow path. Doesn't seem to take to much aiming not to stir up a bunch of sand, capable of syncing, etc.
The motor is water side, which I guess is viewed as a negative, but it's a positive for me and my 20 month old twin boys. Also, noise is completely silent. I don't have temp issues, so heat isn't a problem.
I haven't had any reliability problems with them in the 1 year I've had the tank. Can't speak about longer than that.
And, of course, cost is much, much less compared to vortech.
Great reviews on Amazon too. (There are some negative, but there always are...a 4.4 rating on amazon is really quite good).

Not that I'm doubting the awesomeness of the vortech. While I don't own one, I have no problem believing they are the gold standard. Just a pricey gold standard. That said, the RW-8 moves water around and seems to do it well. I'm not entirely sure what a different wavemaker would do "better", but I'm no expert...
