I have found the greatest source for getting my addis through ebay. She's out of the UK and I get the needles faster than I do when I buy something from the States. She's lightening fast, I don't think I've ever had to wait longer than two weeks. Of course, I can't remember what her site is called at this moment, but if you want to know, I will look it up.
Harry Potter, Knitting, LOTR, Star Wars, Lost, shoes, and CHOCOLATE!
