...can someone post a comparison of the old ball vs the new?
Yes, please do

They should be be in the hands of quite a few folks at this point.
I also would like to make a comment regarding a somewhat derisive post made in reference to V1 in a different thread, by patrickl.
V1,
like version 1 of anything, was the best product it could be at the time, given the circumstances surrounding the development of a new "niche" product. It was the first of it's kind
ever, so we had to take a huge chance on our investment in the product. I searched very hard for a ball made of a material that could be tweaked a bit in manufacturing to provide good functionality, but also one that didn't require us to spend many thousands of dollars on a product for an untested market. I heard "impossible" or got huge price quotes from so many manufacturers that we were fortunate to be able to provide what we could. Based on the majority of positive comments and the quantity we have provided, it's difficult not to think that V1 was a great success. Even so, I never stopped looking to improve it. Now that we have a solid indicator that the market is ready for such a product, we found a reliable manufacturer and have invested those thousands of dollars, making the product even better. It also comes as no surprise that our lead is once again being followed after doing such.
The fact that we were finally able to source these superb new items from a high quality U.S. manufacturer is just icing on the cake. High profit for GGG on the balls isn't as important as the ability to establish a relationship with the manufacturer in the way of more orders, which helps to keep them and their employees around for the next time. Something that is not "a given" considering the current state of factory jobs in the U.S.
These are the reasons why it is important to me that the V2 upgrade to be affordable to all who purchased V1. V2 is the version I would have liked to have offered from the start, but it just was not possible at that time.
On another note, about 4 weeks ago I developed a new trackball mounting method, during the design phase of an upcoming control panel product that we hope to bring to market soon. It is a "high-ball" installation for a 3/4" panel that requires only a few pieces of special hardware and a template (no mounting plate). If you have a router, a drill and the the most rudimentary of skills with them, you will be able to install your EI trackball cleanly and with no big, ugly mounting plates or carriage bolts. Only a small round bezel (in your choice of color) around the ball itself.
The kit will be inexpensive and will be available as soon as I can finish the prototypes.
