Yep I agree with MP, I went over to Pan-Am in Miami earlier this year, filled all the TSA clearance stuff on-line took about 3-4 weeks in total and had no problems at all. Customs were great told them exactly what i was doing and they didn't bat an eyelid, had all the docs i needed..and there you go..easy...!!!
As for Randhem, can't fault them. They never promised me anything and MR has always been straight with me, nice guy....would recommend to anyone.
