My first Amiga 4000 came to me with a WarpEngine 4040, shipped to Florida from Louisiana.
Originally, the seller had a Video Toaster system in it, and he told me he would be removing it and I would be purchasing the 4000D without it. Not a problem.
What he didn't tell me was that he was leaving everything without screws and proper attachments. The hard drive and its bracket were left to roam freely (which he put, by the way, on the Zorro slot side of the daughterboard.)
Needless to say, the WarpEngine needed repair, some parts on the motherboard were broken off, and a Zorro slot was chipped. The guy, of course, simply dropped off the face of the planet.
I traded in the board to Software Hut for a refurbished replacement and was able to perform the repairs on the WarpEngine.
I've been lucky that, in most cases, things I have bought since then have been shipped responsibly. Though on a couple of occasions I have had to say a couple of prayers upon opening a box :-)
