What binoculars do I need to see the Andromeda Galaxy

Away from light pollution under dark skies, you may just be able to see the Andromeda Galaxy (M31) with the unaided eye as a small patch of light. A pair of small binoculars such as 7×50 or 10×50 will show it as a much brighter elongated smudge of light. No detail in the dust lanes will be seen. Why not give it a go. Seeing another Galaxy (no matter how faint) for the first time is quite an experience.
