Which gel brands do you use in your salon? (Europe)

[aurorealis]

I want to invest in a gel (sculpting not polish) system this summer, which I could use to practice, do my own nails and build a portfolio. Because each brand has their own lights, I want to invest in a brand I could use on clients after opening my own salon (I'm still training to become a professional). I'm interested to know which brands you use in your own salon (preferably salons from Europe), because there are so many different brands and I don't know what to pick.

Any help would be much appreciated.
