don't know if I'll be of much help to you pindle.
We bought a Infa axcess change table from Big W when it was on special. It has wheels, and the bath underneath the change pad.
I was looking at buying one of the trays, but for us, we decided the change table would be better for a couple of reasons,

Mainly because of the bath, and me having a c/s means I won't have to get down on the floor to the big bathtub. It has wheels, so if I get stuck by myself, I can wheel the change table out of the room to the sink to drain the water.

I like the idea of the shelves and being able to pull them out. I like the idea that when we do eventually set it up, I can store some clothes for bub, along with towels, face washers, wipes, nappies, creams etc in the change table shelves. Keeping everything in the one place will make it easier to find, especially if I'm not in the room and want DD to grab something for me.

I think the only problem I might have is actually getting bub out of the bath, and then putting the top down to dress him on. I have read that some people don't use the bath part of it much, as their bub grows out of it quickly, but by then I'll be fine to get down on the floor
