    I'd go for the crane every time; it should only run a couple of hundred
bucks, is 100% safe and will place the tower safely on the ground. 

    While Option 2 sounds reasonable, I'm not too crazy about it personally. 

      I think a ten foot section weighs about 80 pounds (110#?), might be a
little more.

     Removing any used, unknown tower is about the most dangerous activity in
which you can participate. I'd recommend being leery of EVERYTHING.
