No problem, only problem is finding the right forum for it, if there's enough interest we might even set up a classifieds/trade forum.
I can certainly say that I'd be interested in one. I am always upgrading versions of this or that, or buying a boxed set that I already have a movie or two from the set already.
Not to mention that I may have something in Region 1 that someone in the UK may not have and want, and I'm always looking for something that's Region 2 and might be able to get from someone used cheaper than importing.
Plus, my to-watch pile is huge, I'm sure there's going to be some in there I don't like and someone may want as I watch them and decide if they are keepers or not.
