Rio or Skybook sportsbook

[Hockeyislife]

Does anyone know if Rio and Skybook are reputable sportsbooks? I heard Rio bought Skybook so if I open which one should I go with? I would think Rio but I have difficulty going to their website. Does anyone know what happened to Dunes sportbook?

Rio did take over Skybook when, from what I heard, they were struggling a little bit. Rio is a solid book.
Dunes is a book you want to stay as far away from as you can. They started out well, but had serious management trouble and ended up in all kinds of turmoil, the result was slooooooow payouts and in fact no payouts for many. They are still trying to get the ship back on track - advertising for new customers, but all indications are they are still a mess. Stay away.
