I am not a collecter, I cannot afford to be.
However, a collection sort of "just happens".
My first amiga was a 1200 bought a month or two after they were launched, so new that the only software included was the operating system, the price of hardware and software was such that I did not do much with the amiga and it found it's way to the back of a cupboard.
A couple of years ago I decided to expand my 1200 and looked on ebay for an accelerator card, I bought a1200 with a 1260 inside it.
Adding a cd drive to a 1200 is neither easy nor pretty, so my next purchase was a 4000D, for which I subsequently bought a 3640 cpu card.
so, as I said it just takes you by surprise.
But I would never beg for a cheaper price for any reason.
