Hi Leahcim,
Thanks for your post. Lots of useful info there.
As you can tell, this is the first time I've been piano shopping, let alone looking for a quality grand. Does the naivete shine through?

Spoke to a couple of piano technicians today, who agree there is little difference between Yamaha's and Kemble's. Conclusion was that, if anything, the Yamaha's will have better resale value due to the durability and recognition of the name. Not that resale value is high on the agenda.
After a bit more thought and research, I'm quite keen on the Yamaha C3 again. I realise it may not be the most prestigious model, but if it's good enough for conservatoires, upmarket hotels, restaurants etc, it won't be too amiss in my parent's house. I can save my dreams of buying a new Steinway for later!
I definitely like the idea of having a brand new piano vs a reconditioned one. I was told today that the sensitivity of the hammer action is something you can never replace, and most recording studios/professionals would use a new piano, rather than an older, more illustrious one. Again, don't know anything about all this, just reiterating what I've been told.
Found a dealership near Oxford that are offering a new C3 for £10,500, which includes all preparation, voicing and delivery. What's more, if I EVER decide to upgrade, I can part exchange for a fixed price of £8660 (original price minus VAT). Then again, don't know how relevant that is, as I probably should be 'scouring the country' if I'm looking for a quality new Steinway/Bose etc.
If you disagree with any of this, for whatever reason, I would be very interested in hearing from you.
Buying a grand is not something you do everyday, so I want to be making the most informed choice I can.
Thanks,
Kaveh
P.S. Will look into Hurstwood Farm Studios - thanks for the link.
