Well I have had a reptibreeze and my honest opinion is that they are total crap. In fact I threw mine away. The door always tried to come off and the frame flexed when I tried to utilize it outside. They rust and the screws unscrew themselves from the frame. The screen that they use is very low quality as well.
Think of it this way... The reptibreeze is a ford focus and the Dragon Strand is a Lexus. That is how different the quality between the two cages is.
There is also the difference in size. Reptibreeze is 24x24x48 while the dragon strand that you are looking at has the same dimensions but is 30 inches wide. The 6 additional inches in width makes a big difference IMO.
Also again you run into are you needing to strip the cage? Why are they getting rid of everything? Most people are not going to disclose that the cages are contaminated and their chameleon actually died.
Personally I would go with the dragon strand and I would strip it and clean it. If you want to go bio active you can and set it up properly. I know the better deal is tempting... But I have learned that cheaping out in this hobby only bites ya in the butt later. Buying quality products that will last you the life of the chameleon and longer is worth while in the long run.
That is my 2 cents
