all five series on dvd

Well seeing as season 4 and 5 haven't been released yet, then those series must be recorded off of TV. And there's not even a picture of the boxsets on there.

I'd never buy anything off ebay unless i could see a pic of the product and the user had over 90% positive feedback.

But it's up to you, really. You don't have to listen to my opinion. ;)
