Bill, the cheapest way to increase your power is to improve the 80m antenna.
We found at several field days that a large (1.25 wave around) horizontal
loop was plenty for nation wide coverage with S9 signal at 5 watts if you
have the room for such a wire.

If you only have a dipole or inverted Vee for 80m, you can add a slant wire
director to an inverted vee and achieve some gain that may be enough for
your regional/national net.
