As of most of you know, I use a heat lamp for my BP. I also use only one hide on the warm side, but a plant that can hide her on the cool end. And also use just one of those crappy hygrometer meters, not the digital. So, which should I focus on getting? I can only get one of the three listed. So, which should I focus on purchasing first?

-UTH & Dimmer
-Digital Hygrometer
-Similar hide on cool end

Over time I will be able to get them all.
