I totally understand what you're saying, but you have to look at it this way.. If you want to learn to play the piano, and build your finger strength up playing weighted keys, then I don't suggest buying an arranger as the firt keyboard... Being a musician can be a steep investment. Of course funds can limit what you'll be playing, but personally I wouldnt buy an arranger for practicing scales.. I'b buy a small 88 key digital.. Those prices have dropped and you can get one now for less than the PSR-2000. If you want to run scales, and learn how to use those keys, I think this is the route to take... Later on you could invest in a more complicated keyboard..... I sold MANY casio arrangers to beginners, and when showing people how to use them, it was like I was talking in another language... So many new players see all those buttons and it scares them. Also having one keyboard and what you get really depends on what you want to do with your music.. I've sold arrangers and had people bring them back because they said it's too much for a beginner to learn, and wanted something that didn't have so many features. Again it depends on your ability and skill level when you start playing. Trust me I know all about the only being able to have one keyboard... I've been playing piano for over 20 years and learned to play on a acoustic piano, now all I have is a PSR-550.. Big difference.... It was all the years of playing the big one first and then moving on to a keyboard that helped me... However it all depends on your budget and what you want to do with the keyboard...
