The FT-2900 usually goes for about $150~$160 and the FT-1900 goes for $130~$140. A brand new, in the box FT-2800 is not worth the same as a new FT-2900. He should be expecting $100~$125 tops. A year or two ago these radios were cheaper but the dollar exchange rate is not going in our favor on imported stuff.
