yep JMB is the Tudor Jedi Master, if you want out of the box though... PureTime sells a 7928. It needs some work and it isn't a super rep by any means. I have one and I had the caseback engraved, new bracelet, new bezel insert. The dial is 'eh ok. Not as crisp as a gen but for $105 for the base it's not the worst place to start.
Sadly one of the problems with the Tudor subs is that you have to spend a lot on them to get 'em to look right. I've seen people spend upwards of a grand on a build only to watch a gen sell for $1800 elsewhere. I have about $200 invested in mine. Tudor made their sub in 4 sizes and there is something for everyone in any price bracket. (I have a list of most of the Tudor sub references and sizes if anyone is interested)
