I would have chosen channeladvsior, I had to flee the Marketworks ship as the 'bad rap' is indeed true. They are expensive. You will see marketworks failings yourself after a few months, and regardless of how big a job it seems it will be worth switching after the first few £1000's you loose in trade because of them. No one in the UK especially should use them, the localisation is not in place. Marketworks are trying to do everything, and in that they are actually doing nothing, as the basic functions of listing items on a 'launch bot' and checkout fail.
