[TenTec] TT 705 Fair Market Value?

[jeff_tentec at burnshome.org]

I just helped the local Boy Scouts purchase a used Jupiter. Now they need a
microphone. I tried a Kenwood MC-50 that they already had, but get no output
at all. 

My TT 705 works great with the Jupiter, and I am considering selling it to
them. If I do sell it I need help establishing fair market value. It looks
good, but not new. The finish is just a little burnished around the PTT
switch. It has a new wind screen. I offered it for sale on this list for $80
and received no offers. Other 705s have been advertised for $60, and were
reported as sold soon after. What is a fair price?
