both Aquazamp and mistking (I have both) are small, but can be expandid on to many misting nozels.
I think that the basic Aquazamp that I now have two of, can expand to 15 nozels for each pump.
the same can be said for the mistking advanced system.
I'm a big fan of mistking. I think that all the parts are pro. for cages, if uesed, the cage corners are more pro and are a finished glossy plastic, while the aquazamp is more like a cheap foam.
then there is the timmers...the mistking is the only one to have a timmer that can work as low as 1 second. this is beyond great for setting up for terrariums (think dart frogs) as you don't want to mist for much longer then 30 sec. while the aquazamp's timer is a GE model that only goes as low as 1 min.
yet again, the timers and all parts are interchangable as they use the same type of hose, nozels, "tees" and "elbows". I would not be suprised if they use the same exact pump...yet ALL mistking parts are made in Canada, while ALL parts for the Aquazamp is made in the USA.
also, both Marty from mistking and Keven Zamp from Aquazamp, will give you above average costomer care if needed. I will say that when I needed my misting systems to be shipped right away due to my new Chameleons that were comming in in just a few days, Kevein went out of his way to send me an email of all the prices for shipping rates for how fast or slow I was willing to do this. he then confermemed everything on the phone with me and made sure I had a few extra parts that I may need and didn't think of.
Keven's website is still new and incomplete but is up and running...

I hope that helped.
