I ordered my new Filo on Sunday from Viking Direct - it was £20.47 including postage. It arrived yesterday morning (Tuesday) - so pretty good!
In this photo you can also see my tabs - this is a set that I found in one of my other personal size binders that I've had since I was seven or eight - they came in a Harry Potter and the Philosopher's Stone Filofax thing, I think, though there's no information on them regarding whether they were actual Filofax brand or what. They're significantly thicker than the Filofax issue ones, which means they're probably a bit more robust.
