Wire beams, my friend. Three-element wire yagis at 40-70 feet will work wonders on 80m. Best if you can make them with straight dipole elements, rather than inverted vees. With an swr analyzer, these antennas are not difficult to construct. From zero-land, you'll need the switchable version. It takes two relays, a power supply and a bit of extra wire to make the beam bidirectional. And, you can be even more fancy with the switching to move the antenna from ssb to cw.
I have a couple of photos, if you'd like them.
