Ask 100 scrappers, you're likely to get 100 different opinions. So here's what I tell my customers.
Get out there and look! You've already won part of the battle deciding which size. That's a great start.
Then you need to decide, strap, post, or ring style.
Personally, I like the post the best. I don't DIS-like the strap, but would only use the strap ones with top loading page protectors (Westrim makes these)
Quality is of course an issue.
Here's my thoughts on some of the more popular brands
Pioneer: Lower end of the price range, quality is okay - if you get the ones with the slip in binding, not the paper binding. (However, Pioneer also offers a guarantee on their albums, I've had 6 replaced when the paper binding has ripped)
CM: Love the quality, hate the strap hinge with slide on pp. Just doesn't work for my style, and I don't like the jeeping. But again you can always substitute the westrim top loading strap hinge pp instead.
CTMH - quite honestly I've never even touched one up close. However, they get RAVE reviews wherever you go. Don't think I've heard a bad thing about them that wasn't related to price.
Dalee: Great album, love the high quality page protectors. Especially now that they've switched to the hidden post design and 3 posts instead of 2.
Scrap Artistry: Great album, page protectors are the same as the dalee ones, hidden post design, only drawback: Two posts instead of 3, but they are short, which leads to the wobblies. Fix: Buy longer ones at the hardware store.
