I've checked about once every year out of curiosity to buy really nice labels. I spent a lot of time on the beer labelizer website and made some awesome ones. In the end, I never ordered. They're not unaffordable for a special event or something. To label as many bottles as I'd need though, it adds up fast. ot was just one more nicety that I didnt have to have.
What has given me the most interest is a gray tone laser printer. That can spit out a ton of labels for cheap, and stick them on with the milk method. Still havent done it, but it's probably first on my list for homebrew.
