My opinion is you get what you pay for. You're always better off spending a little extra and getting much better quality. Otherwise, when the cheaper one breaks, you'll end up spending twice as much. I've personally never heard of that mister so I wouldn't get it. We have our MistKing and we absolutely love it. It works perfectly, never had any issues, it's quiet, and it gets the job done. We got a timer to go with it and it's fantastic. If you have a MistKing, or any quality misting system, you will not need a dripper. If you set your timer properly, the mister will create enough mist to fully coat the leaves in water, giving your chameleons plenty of drinking water. It may take you a few tries to get it just the way you want it, but it's worth it. For us, here in New Jersey, we do some hand misting between mistings in the winter because the air is just so dry. Also, keep in mind that if you get a MistKing, you have the ability to mist up to 15 cages at a time. Not saying you'll have 15 chameleons, but Sean and I started with 1 chameleon then went up to 5 (though we just lost one) and it's been wonderful to be able to alter our system and add nozzles and tubing.
If I were you though, I'd order directly from MistKing if you end up going with it only because if you DO have any issues, you can talk directly to them rather than going through a middle man, you know what I mean? Just my honest opinion.
