This may sound like a stupid question but, do you have a Wal-Mart or lowes near you? There is a digital thermo-hygro by accurite for around $8/ 9 that is pretty accurate. Don't leave it in the cage full time though. I use this one when setting up a new cage to compare readings across my temp controller and temp gun. I compare the rh on this to the rh on my dehumidifier too when needed.
