Hahaha, thanks!! I've got to make a decision soon. No new snakes til enclosures are upgraded and consolidated, so the sooner I do that, the sooner I get new snakes!! Hahaha.
I hear you on the mistakes too. I turned a 4'x6'x6' closet into my ferret enclosure, built myself. I put ramps and tunnels and a dig box and all sorts of cool stuff, they love it. But if I did it again I would change a handful of things to make it easier on myself come cleaning time.
