I would never use a solarium because of the dangers of skin cancer. Solariums are really bad for that!
Also, I suffer from dry skin and when I used to go (in my late teens) it used to sting my skin!! That cant be good!
I use fake tan, the one which is a body lotion, but has a small amount of self tan in it. It brings a really natural colour, you dont have to wait for it to dry and is slowly builds a tan.... And it is cheap!
Cant remember the damn name of it though... when I do I will post it on here!
