I originally sold the Boaphiles because all the herpcages my ATBs are in are white and I liked Proline (NW Constrictors) caging that I already had and wanted everything to match white. The old Proline caging is great but does sag if anything heavy is put on top (learned this the hard way) even with the center divide. I got some of his new style cage stacks but he changed the material used which is now quite porous and I have had issues with staining which I am not happy about.
So I got a Freedom Breeder rack to replace the Boaphiles which I've been using for the last 4 years and it just isn't working for me. My set up/room doesn't allow me to full pull out the drawers and I hate the rounded corners with the bedding I use. I will be selling that (hopefully) before I move and getting some AP caging instead. Looks like I'll be back to having both white and black caging again. Oh well.
Good luck with whatever you decide!
AP makes white caging too, so you should still be able to match your existing caging. I hate to read that about the pro-line caging now staining...I had been considering that company for an upgrade cage for my carpet, but not if his material is porous.
