FWIW guys...
I spoke at length with Steve recently, and he said he doesn't know when but that one of these days he's gonna pull the pin on doing this stuff and actually retire. He said "I started doing this years ago" when I was done working the first time.
He also said,
if you know guys who want Boosters done now, you better tell them to get them into me because I likely won't be doing this much longer. He asked that I pass that along here so I guess now's the time.
I sent mine in days after he told me that.
