Quite honestly....
I'm pleased with godaddy, they give me discount club for free because I do so much auction business with them.
I get my domains at a reasonable price but I could save a buck per domain by moving to canspace. However with the poor bulk tools they have I would gladly pay more and stay at godaddy. With them I can do most anything in bulk and I have not found one registrar with bulk tools to rival godaddy.
I am anxiously awaiting the dan.com move to a registrar but they will charge in USD (at cost) so I have to do the conversion to see if that is worth it to me. Doing accounting with constant USD conversions sucks because I have to wait until the credit card finishes posting before I know what my true cost is.
