betnow offering 125% cash. Just don't live bet or hit their soft lines and you should be ok.
betany offering 100% fp. They will pay but will also spool you and may require excessive KYC.
betus pretty much the same situation as betany
bookmaker small bonuses but reliable.
youwager fairly small bonuses available. Will also tax you 2.5% on withdrawals and sometimes require excessive KYC.
As far as bonus books go, that's about it right now. I did not include books that I think will stiff you or do excessively shady shit.
I also did not include excellent books that don't have bonuses, like bol or 105.
