As far as I know, each and every brand has their very own touch and finish.
Some brands have harder and sturdier keys, some have much lighter keys upon pressing.
Why don't you try visiting some physical shops to test the feel and then decide on which brand to get.
Survey some online refurbished shops as well.
crash course for u
two types of pianos in the market that can definitely last up to grade 8 or higher
acoustic and digitals
1. acoustic
to answer your question
refurbished = used pianos, but get touched up/repaired by the shop so it looks new, usually this is the safer option as they wouldnt take unrepairable pianos eg cracked soundboards
used = probably can get better deal but u better know what u are checking for, its like shopping for a used car, better get someone with knowledge to test the piano out
new = safest option but cost a lot more
acoustic piano comes in 2 variants
(i) upright/upright grands
as it name sake, what u usually see in many people homes, the cupboard like piano
it has two sizes which differs from the length of the soundboard held vertically
normal upright (cheapest and smallest) by height, the sound generally is thinner
upright grands, this is what i would recommend to get
(ii) grand pianos
the cream of the crop of the piano world, these pianos are what u normally see professional pianist playing, the soundboard is horizontal which makes them larger and unsuitable for small spaces
also comes in two sizes: baby grand and grand pianos
brands u cant go wrong: kawai or yamaha
price range: budget yourself around 10k for a proper one, dont skimp on the quality. a good acoustic can last even to your grand kids in a well kept condition.
2. digitals
digitals has 2 types: keyboard and digital pianos
what u need to know the difference are: keyboard has soft touch/action as opposed to a solid/harder action in digital which tries to emulate an acoustic as much as possible
if u are in the market for a digital, make sure to get a digital piano instead, when in doubt, ask the shopkeeper to recommend
brands u cant go wrong: casio, yamaha, roland
price range: 2-3k for an entry level and up to 10k for high end ones
pros: practice whenever u want, because the sound are sourced from high end piano, the sound quality is theoretically better than acoustics
cons: electronic stuffs dont last as long
at first was planning to get a digital one...with full hammer weight keys...but as you said...electronic cant last...it might failed anything after warranty period.
so the latest decision is on Upright piano...most probably will go for refurbished version...
was in dilemma cos I know nothing about piano....just wanna buy one for my kid that will start her lesson soon...
wan looking around kawai, yamaha...now the latest pearl river(saw alot good feedback about this brand)?
i saw some only 2 pedals...
which one is future proof for advance? for eg further grading usage...
