There is also the US Tower MA series of tubular towers. Add the self supporting rotor base and the raising (tilt-over) fixture and life is pretty good.
Shipping can be expensive with any tower that has to be delivered and you usually are responsible for getting it off the truck from what I understand.
If you can find a crank up locally, they can be moved inexpensively with a rented boat trailer of 20ft or so.
We did once bring a 40ft or so crank up back from eastern WA. lashed down to the roof of an old van...THAT was an experience!!
