I use only CM albums. I just became a CMC, but that was 10 days ago, and I have been scrapbooking for 3 years. I just don't want anyone to think I am so biased for CM stuff because that is the rap a lot of CMCs get on message boards.
I priced out the Westrim, which is supposedly the SAME as the CM before I signed my agreement (going into this with my eyes open, etc...). I don't think it is, nor do I think it looks as nice, but the price was not that much different in the end. I looked at Michaels, and the LSS, and I found the book more expensive at the LSS (by (1$) - $25.95, but the refills were cheaper - with the refills being $7.50 per package (had to buy two) and then $5.50 for page protectors. The total cost of the whole shebang at the LSS, was $57.45 for the Westrim.
CM Album is 36$ but has 15 pages so you only have to buy 1 refill at $12 to get to 30 pages. Then 2 page protector packs instead of 3 for a total of $15. So, $63 total for the album, etc.... This takes it to the same page count.
When I first started doing the scrapbooking I tried other products. I bought a couple of Westrim albums, and they are not as nice of a feel to the cover, and I really don't think the pages are as nice, and I have held two up to each other and had my hubby look at them. I wanted to get a better deal as Scrapping can be expensive. He picked the CM pages out as well. If they have changed in the last couple of years, ok, but when I looked at them, I could tell a difference.
As far as top Loading, I don't like them. But, they may be right for a lot of people. I am very organized (ok, I have referred to myself as anal on many occasions - not to mention the legions of others who have) and I HAVE to scrap in chronological order, at least on a particular book. So having them out of order is not an issue.
I did price the Mrs. Grossman, and the cover was pretty nice. The 12 x 12 was 27.50 with 20 sheets and 10 refill sheets for 3.50, so probably pretty good bang for the buck if you want a top loading album. I don't like them and would probably never use them because my daughter (3 years) drags them around and turns them upside down, and I have had things fall out of older albums that were done like that.
Good Luck
