I think it would be a good buy. The basic cage on its own is very good - without any of the tubes etc. I had a cage the same size (almost exactly the same cage but smaller bar spacing) - I used a large flat roof house in it and that doubled up as a shelf
Something like a shoebox - cut the bottom out and use the lid as a lift off roof/platform to put the food bowl on etc. And cut a hole in for a door. Makes a good nesting box. You could put a bendy bridge tunnel over the door as well (they seem to like a tunnel entrance) and that also makes a ramp up onto the roof.
If the cage comes with toys etc I would wash/disinfect everything well before use and wouldn't use any wood items it comes with - they are hard to disinfect.
