HAHA, My first post here and this topic caused me to do it.
I have grown Aero before and it is my preferred method of growing and I felt I should say a few things.
Those systems you are asking about are not something i would recommend as everyone i have met that purchases prebuilt aero systems does not have an enjoyable experience. Most of the time the systems are built cheaply to save on cost and that is a big no no in Aero. If you are handy enough to build your own, do that. If you would rather purchase a system, I would lean towards another method of growing.
First, realize that there are different types of "aero". True aeroponics would take very high pressure and very small droplet size being sprayed. Basically fogging is true hydroponics and is by far the fastest method of growing, also the most expensive and difficult systems to build. I used a modified version of aero/nft that sprays roots with larger droplets (only using 40psi instead of 80-100) and drains through pvc tubes.
The reason that I used aero is simple. I wanted to try and grow the best final product that i could possibly grow. Therefore, I wanted to use the most advanced system I could find. Basically, I chose to do 3 times as much work to get a final product that was 10-25% better then what i could have done for way less money and much less work.
So take this into account if you decide to go this route:
It is Expensive to set up correctly.
It is a lot of work to setup correctly.
When a problem occurs, it can become disasterous quickly.
Once it is setup, there is little to no work to do, probably the easiest system to maintain on a day to day basis.
Growth rates are great.
It is expensive (did i say that already?)
Ask if you want to know anything specific. I consider myself a bit of an aero head.
