Well, half the people at the wedding give blenders. Usually, they are the good blenders though. It's not like people are going to give cheap ones that can barely blend powder and juice for a wedding gift. Besides, blenders are a hell of a lot more practical than china, yet everyone always registers for that.
Many blenders come with food processor attachments. Besides, hummus is very easy to make with a blender anyway since it is soft. I don't really use food processors though. For chopping, always do that by hand since it make a big difference in the flavor. Food processors are also a real pain in the ass to clean.
