I am ordering elements from two China manufacturers this week. I am curious to see how they compare to each other.

I went to order the $12.50, 8mm elements and they were out of stock and were not planning on making any more soon. I did not check the $64.80, 8mm for stock.
Due to the rare nature of the 8mm elements, I will be modifying 10mm elements as they are plentiful.

One company has 10mm elements for $13.50ea and the other @ 11.85ea, with $50.00 shipping for each company.

I now have a sample 10mm element that I will take to the grinder today to physically show them what I want to do.

I figure I have another 6 hours of figuring before I will have the specks to have the barrels and plungers modified. My output target @ 85% rack travel is 90cc per 1000 strokes.

I will also be able to cut down the cam a bunch which will help with higher RPM operation.
