[Unanswered]  stadium ease of transport

im looking to get into the hobby, one of the main reasons being that im going to japan so i will be able to buy stuff for much cheaper, i was planning on not buying a stadium there since it would take up a lot of space and i could just get one here, but looking at the offerings from hasbro and import stores, im second guessing that plan, i can tell just by looking at them that the bucket and portable ones suck, but hasbro doesn't sell a stadium on its own, just the combo for around $50. where i could buy a stadium in japan for around $20, so im wondering if anybody has any experience bringing stadiums back from a trip, and if so how much space they will take up, cause im not only getting beyblade stuff, so it is competing with other stuff for bag space, thanks for any advise!
