The current Cherry model equivalent to mine costs just over £100.

I smiled at "not worth spending any more time": when I opened the case I
discovered that the two ribbon cables which connect the main board to a
(fixed) sub-board don't have proper connectors but are fitted with the bare
wires pushed into soldered sockets. Dead easy to pull out, rather less so
to refit...
