Becoming a registrar, is it worth it?

[K.Washer]

 So, is it worth becoming a registrar?  I'm sure its different for each

customers and another 1,000 emails every day]

p.s. This is a quiet list, so even lurking doesn't tell you much. Let 
me know if this isn't the place for this kind of question.
