From personal experience:
1: Stefan tried to increase the quoted price the day before he was due to collect my stuff.
2: He refused to show any kind of insurance to cover my goods whilst in his care.
3: He emailed me saying that if anything got confiscated at the border all his customers on that run would be liable to pay a % of the bribe to the customs officer.
As someone said above, you pays your money & takes your chances.
