I've had one with the British Mod for about two years. I love it. Use it all the time when tracking: vocals, bass guitar (works great in conjunction with a top shelf DI). At mixdown I tend to use it on voice, bass, kick drum. It's one of my faves. Every studio should have at least one. Opto mode tends to be one of the most used settings. It also does really cool things to a room mic track at mixdown in Nuke mode.
