I saw the bookend in out local Virgin at the weekend (someone had busted open the packaging). They looked to be good quality and pretty heavy (probably explains the R1 costs as shipping them must cost a bit more than usual.
There are similar to the quality of those 'wizard' status things you get in H. Samuels (the jewllers). Looked pretty impressive but I really want the R1 disks and I;'m not sure that an extra £20 for some 6inch high bookends is really worth it.
The packaging looks great and the bookends are look and feel really nice, I suppose it comes down to do you want to pay for them. If its your sort of thing then go for it.
