I'm in Australia, and I've taken to several brands to get the colours I want: Gamblin 1980 is very nice, also Schmincke College Oils. I also use Art Prism/Art Spectrum, although these are a little thinner, along with Marie's Economical Oils (make sure they are genuine, several places sell rip-offs). For beginning, Mont Marte makes a decent set of oil paints, as well as gesso. For brushes, I got Omega (series 51) and NEEF brushes. Canvas I use a range of brands, but the ones I like best are Born (380gsm), and Mont Marte (280gsm).
