The IC-7300 is a big seller but there have been many reasonably priced big sellers over the years, many Heathkit models, Kenwood TS-520, TS-530, TS-830, etc. Back in the 70's I remember the ICOM IC-701 being a big seller, then the IC-706 series, IC-7000, and numerous other ICOM models. And of course the very successful Yaesu Ft-101 series, and many other Yaesu models.
