I have a music store in Southern California and I sell most all the portable digital pianos.
First, for weight and low price there are the Casio Privia 100 (27 lbs) and Privia 300. 32 note polyphony, decent sounds, midi and can have two pedal jacks. The 300 adds line outs and 168 sounds compared to 32. Both have built in speakers.Both keyboards can split, layer and have drum machines and background patterns if wanted. Prices are $499.00 to $649.00 brand new! Pretty amazing products!
Next, the Yamaha P60, and P90 are both very good with the P90 having Yamaha's 3 samples per key, 64 voice polyphony with splits and layers. The P60 is 32 note polyphony, no splits. The one major thing different about the Yamaha's are that they are both still made in Japan, which is becoming increasingly rare given the price differences from China, Italy, etc. The Yamaha P90 weighs more like 35lbs. or so. The Yamaha's sell from $749.00 to $999.00
The Rolands are a bit more expensive with the FP series but all have at least 64 voice polyphony and the new RD300 and RD700SX's have 128 voice polyphony. The Rolands have great sounds, their famous "jazz Scatt voices" all split, are a little heavier to carry around and are either made in Italy or Japan.
Generalmusic makes the most realistic sounding piano to date with the Promega series. The Promega 3 is their flagship with 320 note polyphony , moving slideers and a very beautiful "old school" look (big knobs and easy to use). It's technology is several in one. Samples, physical modeling, natural string resonance all contribute to the most amazing fazioli and steinway sounds you've ever heard. The rhodes and wurlitzer electric pianos are completely physical modeled (no samples here!) There is also a Promega 2 model which doesn't have the moving sliders, 160note polyphony, less sounds and a slightly different key feel. Prices are from about $1800.00 to $2500.00. Not quite as light, between 40 and 55lbs.
All these keyboards feature graded hammer weighted keyboards for the most realistic piano feels.
