Hi Pavel,
I'm using the misting system sold by MistKing. This is a really great system as it delivers a very fine, yet copious mist. I use an automatic timer set to turn the misting system on three times a day, for 1 minute each. I use two nozzles in my 55 gallon tank. The two nozzles are virtually good enough really wet down everything in the tank. All the plants collect alot of water, and my orchids love the misting.
The misting system is not hard to maintain, inface I never touch it. I've only had it for 6 months and I use distilled water to avoid mineral deposits. Its very easy to instal. THe web site instructs you to drill holes so you can screw in the nozzles, I just burned holes into the plastic liner of my glass top, and there they are. I used a regular Poland Spring gallon bottle as my reservoir, again I burned a hole at the bottom so I could screw in my bulkhead, and I fill the bottle with distilled water whenever it starts to get empty. I bought the kit from Mist King, and everything I needed, plus a few extra supplies which I felt didnt go anywhere (like a typical guy I always have extra pieces when Im finished building something

), was included.
I also use hand spray bottles for my other tanks becuase they are not big enough in my opinion to warrent a misting system. Well, my 29 gallon vivarium is big enough and maybe I will get one for it someday.
Prices for Mist King mysting system are on his website.
Hope I answered all your questions. I can't compare MistKing to anyother system as I have never tried any other system.
