Also try E-Bogu, that's where I get my kit from. One thing to note, just in case it's pertinent, traditionally white kit is worn by women or for summer use only. Of course, this is an old-fashioned attitude and has probably changed for non-koryu.
I agree with Sukerin on checking out E-Bogu. Their stock is pretty affordable, and seems to be good quality for the price, as well. And as far as the wearing all white being for women and for summer use, I believe that is not the case for Jodo, so it may also depend on the art.
