I'd really like to take the next step up from my homemade racks to something more space-efficient and professional. These racks, from the looks of them, look like a good middle of the road rack. Until I can afford ARS, these might be it.

Does anyone have them? What can you say about them, good or bad? Could I get some pictures of the areas where the tubs slide in, the panel above the tub that makes the 'ceiling', and the heating system in place? I can't find detailed enough pictures on the site, and am curious as to how exactly they are set up and how they work compared to any other rack. Any gaps or spaces? How's humidity in them?

Thanks!
