Since you live in a condo, the digital piano is very practical. Most of the digital pianos nowadays are RSM compliant. The feel is very much close to the real thing even though the sound is very digitized. You'll spend more time on a digital piano because it will not make you feel guilty for waking up the neighbours. Maintenance is very straightforward. No need to tune. Only need to apply special grease for the keys every year. This service gonna cost you around RM90 to RM100 per year. You can let the kids thrash the clavinova and you can still afford to smile. On the other hand, if you still like the upright piano you have to do soundproofing. This is a must. Then, selecting a good used/recond unit is not easy. Pianos don't like to be moved around. This will affect its structure thus overall sound quality. If the price is right and within your budget, then by all means please proceed. I don't like to scare you but Steinways are not cheap especially in our country. Nothing less than 100K. The popular model like the baby grand series S cost around a brand new 320i. I'll buy a special house just to keep my Steinway if I were you.
