That Emporium website is awful...but I'm sure that has no bearing on the quality of their service. I can't find the prices for the Graham Slee products and no mention of how much delivery would be, I'll try and give them a call at lunchtime.
Lordsummit, I agree that the SE version just looks like it's in a nicer case so I think the standard issue is the one to go for.
Thanks again
