Tower Advice, Please

[HOAGLIN at HUSC15.HARVARD.EDU]

This summer I hope to put up my first tower.  For a variety of
reasons (suburban lot, etc.), a self-supporting, crank-up,
fold-over tower seems attractive.  One possibility is the
U.S. Tower MA-40.  I'd appreciate hearing from anyone who has
experience with MA-series towers, especially with the MAB
freestanding-type base or the MARB freestanding rotor base.
Advice on other towers that I should (or should not!) consider
would also be welcome.  Many thanks.
