Osborne 1: 1430
For comparison, I bought an Osborne 1 in the US in the Fall of
'82. I bought with it an Epson MX-80 Graftrax, and a 300 baud Hayes
Smartmodem. I didn't pay anywhere near USD2800 for the whole setup;
if memory serves, it was much closer to USD1800.
The point of my comment is that these US-made machines seem to have
been more expensive in the UK than the US -- hardly surprising.
Figuring out what UK prices were in equivalent USD is fairly simple,
but figuring out US prices from that list isn't trivial.
