Personally I don't care what age group any of these arranger companies are targeting...the bottom line is, does the model/brand I buy work for
my needs?
If it does, then that's all that's important to me.
I bought my Yamaha Tyros4 over two years ago, and it's sounds, styles, and features, still impress and please me when I sit down to play, do some recording, or customize styles to give my music it's own stamp.
What matters to me is the
enjoyment I get from playing it, whether it's for personal use, or out making money on gigs. Reliability and factory/third party follow-up/support are also high on my list of requirements, and the Tyros4 meets or exceeds them in
all areas.

To me, it was an
investment...the return on it has been more than substantial.
