Well Jim in this day and age things can be costly (I'm 16 so yes $60 is) but if you feel that get reptie fogger, or if you like diy then make one with a cheap ultra sonic fogger or a fogger head and a tub. If the diy just look up on YouTube if you don't get the store bought humidifier (has to say ultra sonic on it) attach a hose and run that into your tank. Then there's the other one buy a ultra sonic fogger with a float, computer fan, and tubing also a big tub with a tight lid. Take the tub mark were the hose will be Mark it then put the fan on the otherside of the lid (make sure it's a water proof one) a tiny hole for the power cable of the fogger and it's done just glue or find a way to keep the hose in place and tight so the mist doesn't escape. The fan is turned on then the ultra sonic fogger. It take a bit too kick in depending on the amount of heads it has but the fan blows air in (forgot to say put it on so it blows in not out) forcing the mist up the tube into whatever you need. That's the harder but more diy route sorry for being long
