Thank you all so much for helping me out on this. I did find a good deal on bulk Organ needles on Amazon, paying less than 65 cents each. I could have saved even more but I decided to go with the titanium.
I also found a great deal on the Schmetz which I will probably order next time, but my DH wanted me to get the ones "made for my machine". Since I had a gift card for $50, I went along with him on it this time.
