Flossie's cage is like this and I wouldn't say it's a pain to clean, taking me the best part of 15 minutes on average. I must stress to watch out for cages with plastic shelves in place as many can so easily break whilst you're scrubbing them (saw you mentioned that as a con for the second cage - that would mean BIG no-no for me). Make sure the shelving is thick and sturdy, as if your rat pees on them, they do need to be scrubbed quite hard to get clean, and there's nothing worse than having them break on you!

Good luck in your decision.
