vision cages

[lmass49]

I purchased a great looking brizilion rainbow boa thats about five mounth old now. I keep him in a glass tank with the top covered a little more than half way. So far I have had no problems keeping the humidity up so it seems to be a ok method. Lately i have been looking at lager enclosures for the future. I like to show off my enclosures so I was looking for something rather than rubbermades. I was looking at vision cages and woundering how well they hold humidity and temps. I have had no experience with these cages so I was wondering if any one could give me any advice. Are vision cages any good or should I just buy a lager glass tank when I need to.
