Thanks for the suggestions!

Actually I do tell this to my customers as well, AND recommend them to sell their old equipment themselfs. When you sell to the new end user you will get the maximum out of it, else one or when shipping to the US, two shops have to make some money, and give warranty etc. Not worthwhile for equipment that I can’t install / is no market for under my customers.
Is this true for trade-ins as well? E.g. if I buy a new KT74, I can trade in a working KT76A or KT76C. Would I be better off selling them directly to a customer in the US using eBay or somesuch?
IME you get a lot more selling it separately.
I have sold at least $10k of stuff on US ebay at prices consistently well above what e. g. SE Aerospace offered me.
OTOH it is more work to create the listing etc. And the usual ebay hassles potentially.
Sometimes you can sell direct to someone. Try the for sale section on some US site. Often the person is actually a dealer in disguise but do you care 
I got 2.5k for my 10 year old KCS55 kit.

Yes! A working KT-76A trade in on a KT-74 would be 225 USD, excluding shipping back. You should be able to get more then 225 USD excluding shipping in the UK to private customer.
When starting with mode S upgrades a traded in quite some KT-76 models. I tested them before the got removed. When shipping these the some large firms in the USA (with 10 at a time) they just would says, sorry 9 are out of spec (while they were not, when measured when removed), so we can ship them back on your expense, or we can keep them and toss them away here. As I do carefull shipping, I highly doubt that they where being honest, so I stopped working like that.
If you have a unit removed, and it’s fine, just sell it online, to another private individual, you both get a better deal, and likely this guy is happy with your unit.
There are also American companies travelling trough Europe. I have seen some prices they offer, but those are really low as well. For that kind of money, my low offers are even high. I can not make higher offers for equipment I can’t reinstall. This is different on equipment that can be used here. So I always encourage my customers to try and sell that kind of equipment themselfs.

Why doesn’t that surprise me?
I think about half of the world’s shysters and flakes have bought/sold in aviation or are currently doing so. Certainty so in the US. The odd thing is that you also find some of the world’s most honest people in aviation, I suppose the situation results from it being such an emotional field.
I have a KT76a transponder and wouldn’t mind having a spare, I already have spares for my nav and 760 channel comm bought at low cost. The thing that prevents me (annoyingly) from getting a cheap spare transponder is that the labor required for ADS-B Out in 2020 will be less if I go to Mode S versus UAT. In every other way I’d prefer UAT… so for now I do nothing but wait for others to work out the bugs.
As said before, the Barnstormers web site is good for finding individual customers if you look out for the plentiful shysters and flakes. The site was started by somebody I know, and has been a huge success.

We weren’t planning to do the replacements immediately, but I’ll keep it in mind!
