Just a note about box calculations. Expect the actual prices to go up by a lot compared to theoretical calculations. Even though shippers like cgw and others use calibrated and sophisticated automated 'dimension-sensing machines', things can easily change when the box is not perfectly solid etc. I shipped a Nexstar 8SE a few years ago, around S$500 in shipping alone. (though at that time, still cheaper than getting it locally lol)
