Just bought a super nice Brady label maker: BMP21-PlusMaker: Ive yet to open I had a bigger version at my previous job and it was awesome!


Brady BMP21 works fantastic, I paid $150 for it over a year ago though. :(

I use a Brady BMP-21 printer with nylon cloth labels for cable wrap labels. They work very well for wrapping around cables and will not peel up like some others do.
