I totally agree. I need to find my toys visually appealing, or else they don't do as much for me. I want to feel happy about whatever I'm sticking in/using on my body, or else I just can't get into it. Still, I've noticed that if a toy's ugly but it does a GOOD job, I suddenly find it a lot prettier, heh.
Depends on what you mean by "ugly." A toy that's designed well can have a very "means business" look that isn't initially beautiful, but once you realize what it does it starts looking much better. I've heard that the Jollies toys were/are in this category.
