Welcome to Just Plane Trading Ltd seems to buy and sell a lot. I've bought and sold a fair bit through him, and have found him friendly and straight to deal with. His prices aren't particularly high - which is good if you're buying, and less good if you're selling - but he does tend to shift his stock, unlike quite a lot of the other brokers, who seem to have the same old ironmongery for sale, year in, year out.
There seems to be a fair bit of denial amongst owners at the moment as to where prices are, right now and the sad reality (for me as an owner, just like all the other owners) is that the market will not pay the same prices today, for our 30-40 year old machinary, as it did 2 years ago.
Planecheck seems a strong clearing house for stock into europe, but I don't know how much is actually selling at the prices being quoted.
