Finally managed to get a Yamaha C3M (2012 model) for daughter.
We had tough time in finding a preowned or refurbished upright / Grand within our budget. Also the complexity of delivery to first floor put me off from buying an Acoustic. Once I bought a Yamaha U3 upright, but piano movers failed to get it past ground floor due to tight stairs.
So I've decided to buy a new piano from a dealer who guarantee secure and safe delivery to first floor. This morning we have taken the delivery of new Yamaha C3M.
I've the delivery documented fully and uploaded in case anyone like to see. This could be helpful (at least some tips) for someone who wants to get a Grand to first floor via balcony
