Excerpt: Let's take a look at the PSR E333 keyboard. If you're looking for a beginner's keyboard this is a pretty good one. Instead of buying cheaper models like the PSR E233, perhaps you can spend just a little more for a better keyboard. For instance the Yamaha PSR E233 has no touch response. To me this is a no-no in any keyboard. Why not invest a little more and buy the Yamaha PSR-E333? In any case, a lot depends on your budget.
