I have 4 cotton perches, 3 plastic perches covered in cohesive tape as cushioning for Sweetie's foot problems, two grainy nail trim style perches for Lemon's nail problem (which thankfully Sweetie doesn't like to sit on), A wooden ladder horizontally also with cohesive tape, a wooden platform, and a natural wooden perch at the bottom. Outside the cage is another cotton perch and a wooden U-shaped perch by the door with more cohesive tape.
For toys I've the dangle one at the bottom for shredding, the chain ball one I've stuffed with colourful paper for pulling fun, the classic disco ball, chain of rings, and near the top two new toys - a swing with a mirror and a triangle toy that has bells, balls, and mirrors on it. I've also put in a 'paper fan' which the budgies can also shred up.
Moira, it looks great I really like the look of those Vision cages. They seem good quality too, when I've seen them in person. The set up looks fun for Lemon and Sweetie . I'd love a budgie sized boing!
