I had a very good experience with EMECO for ticketing my AONE5.
All contacts were made by e-mail and all e-mails were answered within 24 hours.
They woudl not take a credit card number over the hpone or e-mail, only in person. I ended-up wiring the money because not having paid would have left me vulnerable to any price hike. The wire wroked fine and the ticket was FedEx'ed to me within five working days.
