Have there been any recent developments?

I've gone through numerous threads regarding the rebuilding of the stock power steering box. However, I thought I'd inquire again to see if there have been any recent developments, such as companies falling out of favor, changing ownership, or going out of business, which might affect the quality of their products. I'm particularly interested in AGR, Blue Top, Lee's, and PSC. Shipping is a consideration for me since I'll need to send the item out for service and then cover the return shipping costs, of course.
