It's not lightweight, but I really love my front-opening exo-terras. They are really nice to look at -- I put in lots of decorations and real and artificial pants. Easy to clean and easy to maintain humidity when the top is mostly covered. I bought one on discount at a reptile store-- I asked them when they would go on sale. I bought the other one used on Craigslist and just scrubbed and cleaned it well and put it in the sun before using it.
