Something else you could try, if you haven't already... It looks like you already have a plexiglass or glass lid on top, or at least part of it. You could add foil to the entire top, with just a circle cut out of it for your CHE. I would cut the hole in the file just about 1/8" smaller than the dome of your CHE, that will keep a little more humidity inside for you.
I can't speak to the T1, but I have a T8 and could not be happier. I am using a T8 with RHP's and flexwatt for backup, but it's rarely on at all. With just a small water bowl, no misting, my humidity stays between 50-60%. During shed and winter I'll put a second water bowl in there and it will help bring the humidity up another 10%. Aside from my thermostat, the T8 was the best investment I've made in regards to my BP.
