"use of all 3 peddles" ...Keyboards generally have one pedal. You can add more, but they just slide around on the floor. So get a console. They all have three pedals."realistic grand piano sound with overtones" ... "built in speaker system and sounds" ...Here's where most digital pianos fall flat. They are very disappointing. Their tone generators are terrible, and their built-in speaker systems are inadequate. Your requirements rule out any piano console under $7500 (or any keyboard under $6000).One way to get around that is to use a computer to generate the piano sounds. A laptop computer, sound module, amplifier, speakers, and software will cost anywhere from $900 (used equipment) to $1600 (new). Maybe less if you already have a laptop (or desktop) computer.Add that to a low-cost ($1200) console digital and you're done ... for $2000 - $3000. The computer can generate sounds better than ANY digital piano ... until you get up to the $6000 V-Piano or $7500 to $15000 Avant Grand.
Does anyone know the best places to look for a keyboard these days? I found this site www.ragamuffinmusic.com/best-piano-keyboards-for-the-money which helps but was just wondering. Looking for the best one with 88 keys that is also pretty portable.
