Always worth thinking ahead as good cage well looked after can last a long time!
I think making sort of step levels with smaller ledges or shelves can work well in a barred cage.
I really like all the Ranch house cages stuff too, they have a great range & really good quality.
These little degu shelves are great for filling gaps as are lava ledges which also help keep nails trim when they climb on them.
I think the main thing is to give yourself time to set the cage up well, some things will always change a little depending on what the individual ham likes but having time to do it in advance, experiment a bit & think things through rather than trying to do a rush job when you get your ham is by far the easiest way to go.

Good luck with the birthday hints!
