BetJoint seems to be getting some very positive feedback this past month or so from what I can tell. So they might be worth giving them a try, however please keep in mind that they have only been around for roughly 3 months. I personally wouldn't play their at this time though, because they haven't proven to me that they can survive the long haul just yet.
You made a very fine choice with
BetJamaica. They are part of
TheGreek family of books and are top tier in every way.
Now as far as
Wsex and
Bookmaker goes. Both of those books are places I would recommend to everyone, because they are solid.
