Yes, the lowest bands don't work so well on the Butternut, but you
should be able to find a used one for considerably less than that
price. (I've been seeing them go used for $75-$125).

I've had a Butternut HF6V on my roof for some years now, which wound up
being about 15 feet above the ground, with one radial for 80M, and
about four radials for 40-Meters (and the higher bands). I've had this
antenna at five different locations over the years.
Using it, I've made 5BDXCC (plus 30M DXCC). I only have about 185
countries on 80-Meters with it, and only about 260 countries on
40-Meters with it. Then there's 160-Meters - only about 40 countries so
far.

Some day, I hope to have a real antenna for the lower bands. Right now,
the Butternut is down since there's some building construction going on
at my home, and all I have up now is an 80-Meter Inverted-Vee, which is
now my "all band" antenna. It's up about 25 feet above ground in the
center, five feet above ground on the ends, it's fed with 450-ohm
ladder line. Sometimes it takes me four or five calls to get through
some of the pileups! (H40 on 80-Meters, KH5 on 20M RTTY, etc. in the
last week).

YMMV.....
