Well eBay prices have gone bananas
The cheaper one wasn’t even shown working to any reasonable degree.
Maybe all the chatter on here helps to inflate the prices even more, maybe we need some sort of code to help keep prices low?
That's an interesting thought. There can't be that many potential buyers of some of these things.
I look but I haven't bought a used piece of TE off ebay for years. The prices have generally become far too high, especially for anything small and neat, such as those little RF sig gens which were rebranded by all sorts of people.
If you want something specific, the established dealers are worth a try. Very often they are cheaper than ebay, they offer a short guarantee, and they'd really rather not sell a load of rubbish, unless it really is spares or repairs.
