WOW! didn't realize they could be that strong.Well I decided to go with the plex and I saw the designs for the enclosure you suggested.Its amazing!But you see a DIY person is also a cheap person.So I will probably break down and go for that enclosure when I get my own place.I made my enclosure a little smaller for starters and when my iguana out grows it I'll make it a castle.LOL!My enclosure is now a 2.5'depth by 4'long by 4'tall.I also decided on one viewing window.I'll post pictures when its painted and my iguana is happy.I'm nearly down and it only took a day.
