The Secure X-plus is practically the same diaper as Bambino... just without the baby look... and at a reduced price. If I had to live with one diaper for the rest of my life it would be the Secures. They are absorbant like an Abri without being as thick... the refastenable tapes are awesome for getting that perfect fit... and the price, while a bit steep, is justified by their overall quality.
Just to clarify for those that haven't seen 'em, it's not like the Secures are thin or anything. Their bulk is almost as much as an Abriform X-Plus, and capacity is pretty much the same (the Abris have more cellulose filler, and the Secures have more gel).
I tried a Dry 24/7 a couple weeks ago, and while it was a decent diaper, there are a few drawbacks. To sell them at the price they do, they definitely cheapened out on the padding. What's there is very absorbent, but the padding area doesn't extend much into the wings of the diaper at all (causing leaks out the legs while sitting down). The tapes really aren't anything special, and the crotch isn't as wide as, say, a comparable Abena Super or Secure Plus.
The Abena Super and Secure Plus are undoubtedly better diapers, and the Secure is even cheaper, at 80 cents a diaper (shipped, per case) vs. $1.04 for the Dry 24/7.
As someone else mentioned, the Tranquility ATNs are my favorite "cheap" diaper. They're reasonably absorbent, soft, and thin enough to wear out to work and stuff, and they can be had CHEAP if you look around. I've gotten cases of 96 off Ebay for less than $50 in the past.
