Although we ended up trying eSeller and Marketworks, we never ended up getting launched with them. One had no UK localised support, whilst the other promised implementation in a few weeks and never delivered. I have been with Channel now for almost a month and am up and running 100%. We are working together on getting all of my usernames set-up on one common inventory account and I can now sell into eBay Ireland/AUS/France and Germany. They also have provided me with a store front and my own checkout. I must say they are not as cheap as the others, but so far it's been worth every £.
