The Winsor & Newton Promarkers where the first alcohol based markers I used. And to this day they are still my go to markers. Winsor & Newton Promarkers are great markers for coloring larger areas and blending. They are available in 2 configurations: a bullet nib and a chisel nib (Promarker) and a brush nib and a chisel nib (Promarker Brush). The color selection lacks some really dark colors, but other than that there are many colors to choose from.
