Hi all.
I have seen many power supply recommendations but they are mostly around the USA or Australian, or unknown Chinese brands.
I live in Europe (Latvia, to be more accurate) and I would like to buy a budget (under 150 EUR) power supply for my DIY projects. I'm looking at minimal range of 0-30V 0-5A models. Intended use - various small projects, mostly Raspberry, Beaglebone kind. But also might have some audio equipment or small motors related. So I'm not exactly sure if switching power supply would be able to deal with it?
I know that I could get one from China for really cheap, but I'd like to have at least some minimal warranty.
So, I looked around in Amazon.de and some local shops. Many products from unfamiliar brands (Levelpro, ECO-WORTHY) look like rebranded copies of the same model (at least from outside). If it is a good quality copy of a well known model, then I could go with it, but I can't tell from the looks of it.
One of more-less reliable European manufacturers known to me is Velleman, I already have a soldering station and grinding tool (a.k.a. poor man's Dremel) and they seem to be OK. They have a bunch of lab power supplies with required voltage / current range:

Also they do not specify which ones are linear (although for some of them it is specified that they are switching, but I'm not sure if all the others are linear) - what parameter in the specification should I look at to clearly see if it's linear or not? Is it ripple voltage and what should it be to make the distinction clear?
If you have experience with European manufacturers (of course, I know that they are made in China, but I hope to have at least more or less reliable circuit design and a warranty), then I'd be grateful for any suggestions.
