I've spoken with George a number of times and have some of his molds and sizers and have Zero issues with them. That said, George has been having some health issues lately and is no longer in business and from what I've been told, all he has left is current inventory till it's sold out or someone buys the business.
We have a couple guys making and selling sizers in the North South Skirmish Association as we have to size boolits to the bore for competition purposes. Try this guy-

There is also Tom Crone in the N-SSA. He doesn't have a website and I don't have his contact info handy. His stuff is top notch and he can make anything you want. His sizers are larger than George's in length and are designed to fit into a standard 7/8x14 reloading press and include a lock ring to set the sizer where you like. George's "pusher" is two different designs, pointed and flat, and made from a strong plastic. Tom's are made from steel.
I wouldn't mind trying the Lee but there are no sizes listed that fit my requirements. Tom can make anything you want and I tend to support my fellow N-SSA competitors. I wish George well and hope he can recover.
