I decided to go small scale. The
ebay sync function is not robust and so rather than deal with keeping everything in sync (I tend to edit things fairly often), I am just going to list at most a hundred items there and see how it goes. I'm listing some of my most expensive items. Those don't get edited much - keeping them in sync should be easy. They also don't sell very often, so bookkeeping shouldn't be too bad. Wish me luck.
