Tower 1 - 160 ft Rohn 45 guyed every 40 ft.

2L40 / 2L80 at 160 ft  (or 80M rotary dipole in middle of 2L40)
                        (or pair of 80M inverted vees at 150 ft)
Tribander at 120 ft
2L40 at 80 ft
Tribander at 40 ft.

Tower 2 - 100 ft R45 guyed at 30 / 60 / 100 ft.

Tribander (or big 10M Yagi)  at 115 ft (point 10M 180 deg from 3L40)
3L40 at 100 ft
Tribander at 60 ft    (or 10M)
Tribander at 30+ ft   (or 10M)

Add 90 ft 20M tower with monobanders at 90 / 40 ft  upper / lower / both
          consider third 20M beam at 60 ft fixed somewhere useful

Add 70 ft 15M tower with monobanders at 70 / 40 ft upper / lower / both
        consider third 15M beam at 55 ft fixed somewhere useful

Add rotors to lower antennas until money runs out.
Fixed lower antennas and separate 40 ft tower with 
rotating tribander may be more cost effective.

Be sure to adjust antenna size to be within ratings of the tower!
(Or adjust (increase) tower size to accomodate the antennas you want :-)
