Bought a Razor 65 this year and was amazed at the quality. Last light clarity is incredible and worth every penny. That being said, I don't go over 30 power very often. I haven't looked through the 50 at low light so I don't know how it is with light gathering. Others on here can tell ya better on that but if you're committed to your budget I don't think the extra power above 33 is absolutely necessary.
