Hi Michael,
It's so good to hear you saying "I am well set up" because I remember the difficulties you were facing when you first started out mentioned on the forum. Really glad for you.
It seems that you're not the only one talking about such things as second hand radio prices and Peter Parker VK3YE did a few pieces recently concerning such. He made a video about it and is linked below but remember that although he asked Hams from around the world for the surveys his final prices are in Australian dollars :-

If you notice in the video he also covers CB radios as well which have seen a marked drop in prices over the last few months as well as other pieces of equipment.
Second hand prices seem to take funny turns on many different items and it's almost impossible to figure out why. Maybe it's just a demand thing because older beauties like the Icom IC-706 go for as little money as old Yaesu FT757s and I know which one I'd rather have. (I've loved my FT757 but the IC706 is a phenomenal little rig!)
Certain radios seem to jump in appeal and collectivity so also increase in prices. One such example being the old Yaesu FT101s which used to go for very little money but then fluctuate wildly to often incredibly expensive prices.
I also notice that often people are putting radios up for sale on the likes of eBay but asking for the typical prices found from a dealer. The difference between the dirty, worn, no returns stuff and a cleaner example with a sales return policy by dealers should tempt people into buying the latter. People do love to take a chance though and if someone appears to pay the 'going price' for something everyone else jumps suit. (Just take a look at the number of 'watchers' on some of the eBay stuff and then the flurry of similar items listed afterwards if it appears to sell.)
Also remember that we had a huge jump in the amount of Amateurs becoming licenced with the online exams available during the Covid lockdown period. There was an initial jump in the sort of prices being asked for radios at that time more than likely due to demand but then prices plummeted quite soon afterwards back to similar pre lockdown prices. Some of these Amateurs are now looking about again if they didn't succeed the first time around, bidding on these now reduced priced items and if there's enough of them escalating the prices once more.
I think the apparent 'cost of living crisis' sees Hams trawling through their shelves as well then listing old radios too, often for high prices. You only have to hear the joking quips about electricity costs within the Ham radio community but some sites (I've noticed a few of the KiwiSDR's doing this) go full out about it. Maybe their old junk, ahem sorry, never serviced for forty year items might help them alleviate those bills.
As they say it's a "funny old game" when it comes to second hand prices Michael and sometimes what was once praised highly is now difficult to shift and vice-versa.
Great posting there and enjoyable to respond to but remember, this is just my view and input on things.
(Some get really flustered if your opinion differs to theirs....especially if they're selling!
)
All the best to you there,
Victor
