Oh yes, the light hood is great! The one that I use is for compact bulbs. I think I paid around $40 at Petsmart or Petco. . .have a hard time telling those two places apart.

I don't think your temp/hum guage would stick very well to the glass with the misting system. And I agree it's very nice to be able to move it around. I don't have the misting system, so mine sticks up there just fine and I can take it down and move it around since it's just stuck on with velcro.
That Corallife fan is QUIET. . .I can't hear it at all when it's on, unless it's screwed on to part of my wood hood cover. . .working on this "issue" this weekend. I bought some supplies that I hope will help. lol
P.S. I think I'll eventually buy a couple of the masds that you have on your list too. . .LOVE those jaquar spotted ones. . .I am thinking though that they'll be a bit big for my tank. . .probably need a bigger one, such as the Exo-Terra with the front opening doors. . .It's sooooo easy to justify a "need" for these things. ROFLOL.
