Enjoying too. I very much like my BC wagon but there's nothing magic about it. The green tail vise is what G Hack picked for his dream bench after all. I suspect youll be just fine after a careful install, which they all require. Will say that i vastly prefer square to round after making the switch.
My old bench is DF and no trouble in 10 years.
Good luck and enjoy the massive old iron-- wish i'd been able to use similar.
Cheers,
