content: I would look into a b& k precision used on eBay model 1601. I have two that I had bought on eBay used and I love them. Old technology but still works well for me!

Here in Germany you can get it for 130€ (incl. 19% VAT):http://www.henri.de/stromversorgung/regelbare-netzgeraete/regelbar-0-30v/18783/ps-613-labornetzgeraet-labornetzteil-0-30v-0-2-5a.htmlLook at different shops. I don't know the situation in Denmark, but there are many vendors in the EU which ships to Denmark. For example:http://www.reichelt.com/http://www.tme.eu/

content: I would at least want a multi-turn pot or fine/course adjust for the voltage knob, otherwise setting it to the correct voltage (eg. 3.3 V) can be quite frustrating. The power supply you linked to doesn't have either. In my opinion for $300 you should be able to do better than the cheap Mastech/Velleman/Korad power supplies. You might be able to get a new Agilent U8001A for under $300.If you don't need programmability, then a used analog supply could be a good option. Something likethis power supply(€85 shipped, he may accept a lower offer) seems to match your requirements. Tested and working except the power indicator bulb. I'm not familiar with Sodilec equipment, but it seems fairly popular in France and looks to be well-made. I like an analog panel meter especially for current display, since it will show fluctuating signals much better than the cheap digital panel meters often used in power supplies.Other brands I'd consider would be Lambda, Kepco, HP/Agilent, TTI and Philips. The latter two are European, so may be easier to find. I wouldn't recommend ordering something heavy like a power supply from the US unless you get an exceptional deal. Also keep in mind that not all power supplies can be converted from 110 V to 230 V (Dave even made that mistake once), so check the (service) manual first if you're considering buying one from the US.You could also consider two 30 V / 1 A power supplies (which are somewhat more common). You can always parallel them for 30 V / 2 A. It's not as convenient as having it in a single power supply, but two power supplies can often be very useful. I would definitely prefer two 30 V / 1 A supplies over one 30 V / 2A, so it's worth considering if you can find the former for cheap. Lambda and Philips have some narrow power supplies that don't take up much bench space.
