I would strongly recommend going with either HQ (which includes Congo/Brisbane/Madagascar cages from EN), or the Critter Nation/All Living Things cages. I'm familiar with HQ, but have heard only good things about the CN/ALT cages. Both types are very sturdy, the budget cage you linked doesn't look as sturdy, and it was hard to tell the door style and size.
I have personally had the ENs Madagascar, and currently their Brisbane. I have also had the HQ Lrge Sturdy from Suncoast Gliders. The HQ Lrge Sturdy is very much the same as Congo only it has six additional, sliding, feeding doors on front panel, and does not come with shelves, however the shelves are nice to have and can be purchased separately from EN and fit the HQ Lrge Sturdy cage as well. I used reuseable zip ties on the six front feeder doors as well as the side access doors as on all HQ cages.
