All my albums have been from Spotlight until this one, and they were all Snapload from Grant Archival. I love them.
I've just done some searching though, and it seems you can't get the Grant Snapload rapid refill system in the UK. There is another company which does something similar called Snapload but it starts at £6+ ($9.20) for 1, and in Australia the Grant ones are available for $6 for 3. Heck, the albums were only $15.
I do the post ones, but since my albums are so big I use the long metal posts. I put all of my pages in protectors and when I'm all done with them, I add them all into the book at one time, I do my best to make sure I have everything in order so that I don't have to go back and re-arrange anything once it's in the book. I agree, it takes some practice. . . :-)
