I really think the gt3b looks cheap with the plastic chrome knobs and gawdy large screen.
People love their futabas (they have to, they paid more for them than my first car cost) and this radio has fhss just like futabas.
If you don't set epa's they have a 3 channel model with no computer functions for even cheaper, and a cheap non-computer 2 channel model. Receivers are under $10
