Shipping back home isn't a concern to us - my husband is an officer in the Canadian Forces, and so all of our stuff was shipped here for us, and will be shipped back to Canada in three years time, without costing us anything out-of-pocket. If anything is damaged in transit, we receive full compensation, so again, that's not an issue for us.
The Canadian support base up in Geilenkirchen recommended a multi-system TV, so there must be a good reason why.

The Canadian Forces don't recommend anything without a good reason.

So that's why we're looking for one.
Thanks for all the answers. We were shopping at Conrad today, and the TV guy there said that they didn't carry multi-system TVs. I guess we may end up having to make nice to one of the American officers, so we can go down to the American PX and buy one there (which we can do, but it is supposedly a real hassle for Canadian officers to get on the US base the first time, although we are allowed to shop there.)
