Bet-IBC have pretty irritating dep/wd charges. Rather defeats the point of low juice books imo.
BetinAsia have a really good selection of obscure books in their molly accounts. If you bet football this might be a good choice. Don't know how long they've been around though.
AC88 and PT have been around a while, and are probably the two big names.
Sportmarket I know someone who uses, they seem reputable.
Bet-football I recognise from a while back but don't know anything about.
Personally I use Eastbridge, not had any problems and payouts are basically instant (a few minutes via skrill). They also own vodds and various betting related companies in Asia.
