I guess the important question is, what is your honest budget to get a playable instrument, and what equipment might you already have?
You can drop 150-180EU on the Studiologic, and, on its own, you won’t have an instrument that is playable. You need a sound source/synth module, amp, stand, sustain pedal, and a few cables. If you want to use your computer as a sound source, you need an interface to convert MIDI to USB (and, as pulykamell mentions, to get anything truly enjoyable/lifelike to play, you’ll have to drop a little bit of money on the software). You may already have some of these things, so they might not factor into cost, but it’s important to keep them in mind (as well as how complicated it might be to just sit down and play; "oops, where’d the module go . . . I need 3 outlets to power everything up . . . have to drag in the amp from the other room . . . the battery has gone on my 20 year old synth, now I have to look up online how to open it up and change that . . . etc etc).
Not that I’m trying to be negative, but I usually advise people who are just starting down the road of electronic keyboard ownership to stick with simple solutions . . . they lead to a more enjoyable experience, less frustration, and can often come out to be close to the same cost as an “economical, but with more moving parts” solution, when you finally add it all up.
I don’t know where you are, but if there’s any kind of used market, and you’re not desperate for an instrument right now, those Casio Privias (particularly earlier models; px110, px310) tend to show up every once in a while (or check e-bay if that’s your thing).
Yamaha also has a model (P105), that they released to compete with the Privias; I haven’t heard as much about it, but it might be worth keeping an eye out for.
Just some more things to think about. If I had a dollar for every time I’ve wasted money on gear that was not really what I needed, but was a “good deal,” well, I’d still be out a lot of money, but slightly less. 
The studiologic might be the exact right choice for you, but I’m just playing a bit of devil’s advocate.
