I recently checked Ebay. Lots of choices.

I buy Organ needles on Ebay. Loads of suppliers - choose the cheapest!

A week or so ago an older post came back up and noah or Caroline had posted a response. In that post she said that she bought her Organ needles on line for just $11.95 for 100 needles from a US company on line called ctsusa.com they have free shipping. Though they were not "embroidery" needles and the titanium needles were quite a bit more but for under @$12 for 100 needles then, if a regular needle will work for you then that would be an awesome price. They did have the other types of needles also, but you would need to go take a look. Good Luck Pam

There is a yahoo group that buys needles in bulk for its members. Check out:

I live in Australia but I buy mine from USA and get 100 packs of 10 at a time
