Jane, I have been using Dansco binders for 9 years. I have not had a problem. They do get heavy and they are pricy. I bought all of mine from Charles T Rogers over the years. The only drawback I'd say is that when someone wants to see your collection it can get exhausting. To get around that I scanned all my chips into pages that hold 30 (made the framework myself) each and show that. Then if someone wants to feel the chip...
And, I guess, if anyone wanted to steal your collection they're in for some heavy hauling.
