Not only are they usually cheaper but they’re also much easier to store. For this reason, you might prefer to look into small ultralight aircraft models. I said 'until three days ago' because another team (that included the person responsible for the Zibo 737-800) has released a newer and reportedly improved version of the entire 737 NG series of aircraft.The costs involved with purchasing and storing an aircraft can be prohibitive. This is the default 737-800 substantially modified and made into a near study-level aircraft by a user here on the forums.
