Martin, I have a vague recollection that a Dragon was well north of £2k. They were 4150dm, (Deuchmarks) in the early eighties, and they may well have gone up over £3k, I honestly can’t remember, and I’m having trouble finding a price for them.In wiki I found this:
In the early 1980s Nakamichi came out with further refinements in a successor top-of-the-line machine, the Nakamichi 1000ZXL. Prices pushed upward with this machine being $3,800 at the time (the 1000ZXL Limited was even at $6000). The updated 700ZXL was a mere $3,000. Low-end cassette decks sold new for under $300, with the Nakamichi name on them. This time period stands as the pinnacle for cassette recorders, as from that time onwards digital recording methods began to make inroads.
