wavy sea Vs SCWD
 

Any input from users out there? I am undecided between the two.

Wavy Sea hands down. They can rotate 360 degrees where a SCWD can only alternate between two outlets. Wavy Sea can handle way more flow too. I like the SCWD's and they're cheap but there's no comparison between them and the Wavy Seas.

what is the approximate retail on a wavy sea?

they arent really the same thing at all. one is 40 bucks the other one is 400

I used to have a Sqwd and it did a good job.Replaced it with a wavemaster pro that I got for a good price ( free ) Replaced that with a Wavy sea.
If you dont have the $ 350-$400 to spend,IMO the Sqwd is better than the wavemaster I had.Set up properly they work very well for a cheap price.If you do have the cash,Wavy sea is great,no dead spots in my tank now.
Keep in mind that the larger the pump,the faster the sqwd will switch from side to side.I was running an 800gph closed loop on mine and found the switch rate and flow was just about right for a 3' tank.

The in between choice would be the OM Squirt.

golds has wavy sea's in stock i think around $300 and very cool
