i have an account with simons group and find them pretty good all round. their books are targeted more to americans but do have decent sign up bonuses and reasonable odds so they do attract bettors
income access have a good range to choose from also and i find their setup one of the easiest to navigate, and although there is a thread on here that questions their tracking, i have not had a problem with that at all.
theres lots of good aussie books that have great sign up offers , deposit options, larger limits ,good odds and they have great reputations as well because of our tight laws here, there is no risk of bettors losing funds, as money has to be escrowed to liabilities, which attracts alot of the larger betting money.
cheers
