i have yet to find any cage strategy that is as durable (over a very long term) and affordable as a galvanized trough. they are simply terrific as a base.
since they come either oblong or circular, and we wanted the largest possible cage in the room, circular it was 
triangulating the three together actually makes terrific use of space as well. i have suggested them for homeowners looking to do a "corner" cage, as the circle will nestle into a corner and still offer more square footage than the oblong trough.
i am no handyman, so we had a local guy come in and do the wooden lids, which have also worked very well. there is access from 3 ft. top doors, but the top itself is also hinged near the middle, and the entire thing lifts up pretty easily.
we have had those 10 footers for quite a few years now, and they have held up perfectly, working great for monitor setups, gilas, Uros and more.
