I started out with tanks and quickly became fed up with the constant maintenance. My house is dry during the winter and it was a nightmare keeping the humidity up. now that I have a tub system, which is much more cost effective and easy, I am much happier. I also think my snakes feel more secure. If you are thinking about switching to tubs, my advice is to shell out the money and get a helix or herstat, some heat tape and you will not regret it.
