Sorry man, I missed your bulking thread. I just went and checked it out. Dropped a little comment in there for you too.
Well, if you're dead serious, then power rack it is. What are you waiting for!
But just before you order it, you might want to consider "hip belt squats". I've never done them, but I know some people that do, and they are very well pleased with them. Basically, you wear a belt that attaches to the barbell, leaving the barbell hanging (longways) between your legs (with weights slapped on, of course). Picture it? If not, do a search. As I understand it, it hits the thighs harder, but you miss out on the upper body involvement you get with a standard squat. But that's not really that pressing a concern, 'cos you're still getting the major benefits of squatting (heavy). It's also (I imagine) a lot cheaper than 750EUR, so it's something worth considering.
