I found someone on ebay that you can get 6 pairs of addi turbo needles for about $30. They off the following sizes:
The US size 3 to 7 in 16inch, 24inch and 32inch
The other size 8 to 10 in 16inch and 32inch
The larger size 10.5 to 15 in 32inch
(you can pick whatever combination you want)
They come from Norwich, United Kingdoms shipping GPB is $3.68
They’ve got a good rating 100% with 223 people rating them. I’ve e-mail them with a few question and they answer quickly and very politely. I have bid on some of the needles and am hoping to win. I will let you all know how it goes, but they seem good, with good prices.
