Can you tell us which currency you would prefer? In South African Rands, it's my opinion that 3 Piggs Poker is best but in UK Pounds, I think it's probably
Party Poker. Wild Jack (Prima Poker Network) also has a good reputation and they deal in US Dollars as well.
For newbies, I would also suggest a visit to Bugsys Club. They are associated with the Poker School crowd so there is a long history of helping people.
