After reading many reviews on Amazon and other sites, I decided on the Confer steps (2nd link that FormerBromineUser posted above). I also purchased the curved add-on piece that makes the steps wider. Based on the reviews, I think I'll make some weights out of PVC pipe rather than filling the steps with sand like the instructions tell you to do. I'll never get them pulled back out of the water if they weigh too much! Anna K. I noticed your link to instructions on how to make the weights. Thanks!
