Spyder Robotics!! Herpstat or go home!!! J/K, well sorta. I personally swear by Herpstats but then again I got 4 of them. I also use Hydrofarm ones too but those are mostly for backups.
As for a UTH, me personally, I like Zoo Med stuff but I hate their UTHs. My vote is either for Flukers or Ultratherm for glass tanks or single tubs. For all my AP cages I just use Flexwatt and for my Proline cage, I use a Pro Products RHP. If though you are going to use a Zoo Med one, be sure to buy a roll of aluminum foil tape and tape the sticky side of the UTH so you can just slide it under the tub. That way you can reuse it and move it without trying to peel it off the tub.
