help me choose a digital piano/stage piano

So I am looking to buy a digital piano (stage piano? dont really know the difference between the two) for practice at home, cause I really need a hammer action keyboard.

Since I live in europe probably gonna buy either from Thomann or Digital Village

with the budget that I will be spending I've come up with two choices

the first one is the Korg SP-170

now, everything seems good about this keyboard EXCEPT the fact that it has no buttons, to change a sound you have to hold 3 different keys on the actual keybed, or something like that. that I've read.

If someone has on or has played on I would like to hear your opinions about it. How is the action ?

the second one is a Casio CDP-100

this one I have played at a local music store and it seems quite nice (And it actually has buttons!) but is a bit cheaper than the korg. how does it compare?

I would like to know what do you guys think

Suggestions are accepted as long as it's somewhat in the same price range

c'mon guys :|

For learning on, both the Korg and Casio would be great, much better than learning on a non weighted keyboard. I'm with you on the korg button issue, it seems a bit daft at first but I'm guessing it's down to the fact that a lot of people use the 170 as a MIDI controller and don't use the internal sounds. I've tried a few casio's and they've really come on in the past couple of years, the PX and CDP range have great piano sounds and a good action. It's up to you essentially, I don't think there are any other pianos at that kind of price point with the same features and sounds.

The pianos to consider around are: Casio PX130, Classenti CDP1, and Yamaha YDP141
