I just had a look at the Kawai CN35 JG, it certainly seems a beautiful
instrument.
I don't particularly want a digital piano, but would be quite happy
to upgrade to a small (but 7octaves) upright piano, with pedal, which
I am sadly lacking with the keyboard - and cannot be added as an
extra:
I am lucky that I have no immediate neighbours as such (well, several
metres on either sides, plus hedges etc... and only the cats listening
at home! (unfortunately, but my husband used to love listening to
my efforts!)
There are several second hand uprights for sale, in excellent nick,
but the problem is that they don't deliver, and the cost of transport
might be more than that of the bargain offer!
