Me too. My eyeight isn't as good as it used to be so I like being able to see at a glance what size the sockets are on each peg. I've got 1/4, 3/8 and 1/2 inch versions and it's just a pity they don't match the drawer sizes better.

I got them from our local engineering supplies place - they had to order them in but they were about half the price they were on ebay.
