OOPS!,I looked on QRZ.com,& one bloke in Oregon has a 100MHz HP Oscilloscope for sale,but it's a bit costly,around $350 if I remember correctly.
That was posted about a week ago in their "Online Hamfest" section.
They also have a section showing upcoming Hamfests,but it looks like there is nothing immediate in Florida (You just missed one)
I just realised EEV Blog have their own "For Sale" section,it might be best to look there first.
