I'm a happy owner of a PSR 740. I use the keyboard professionally and play an average of three hours a day. I've never had any paint come off the keyboard.

The PSR 740 has a lot of limitations. I would rather do sequencing on the computer, so I don't care about sequencing. The ability to only have three added styles on board at a time, is a big disadvantage. I have found a quick way to load styles from the floppy, but it isn't ideal.

On the other hand, the vocalizer is an excellent feature, and I wouldn't trade it for any keyboard without a vocalizer. No way!

The PSR 740 is pretty light, and as I do a lot of lugging around this is a major advantage over the more expensive arrangers. If the Casio were about as light, and if Casio put a vocalizer on their keyboard, I would go out and buy it right away.
