Any good swing sets for older kids & frequent moves?

[ClarabelleCowFan]

We would love to get a swing set for our younger 2 kids (ages 4 and 7) to play on outside but we move frequently thanks to the Army so we need something that would be sturdy and not a royal PITA to take apart and transport every year or 2. Does such a thing exist?

Any suggestions? And since this is the Budget Board - the cheaper the price the better!
