Yes E-bay is cheaper.
At Capefear, cost for 10' x 24" film is $59.00 with S/H I think it was. they have much smaller size for sampling but it is pretty pricy!! $19 for 12" x 24".
I pay premium over E-bay because I prefer to have a "regular" supplier. It's the reason I order from DigiKey, and buy Tektronix and HP equipment.
My sample order from Capefear came very prompt. Well packed, looking very reputable.
I do not care for grey market items or suppliers where you can't trace back.
As a reference of how I view things: Some of my cutting tools are cobalt steel with TiN coated material. Not some high carbon steel. Tools themselves, I prefer Dewalt, Bosch, Makita... Prefer it is MADE IN USA or Germany or Japan and not just the label saying USA/German/Japanese company. Most recent outburst was over 6-32 tap. Ordered a replacement tap. Broken one was a cheapie from Craftsman high carbon steel. Flute on the tap was cut so irregular, one of the cutting surface was less than 1/32" wide. Replacement is a cobalt steel, TiN coated 6-32 H3 tap from Ghurring. cost is about $15.00 each.
Been looking for a lathe and mill and I think I'm going to invest in Taig. Not so hot on Smithy or Grizzly. Both are not that accurate. I used Smithy and wasn't impresed. Even their technical spec was bit of a yawn.
