For the absolute top-end premium, $2 is my firm cutoff point. I will buy by the case to reach that. That rules out Rearz and will likely rule out the new Magnifico.
For casual use, I'm very unhappy with everything. For $1.10 each, the ATNs only last for maybe two light uses. It's more expensive to wear them than premium products because you have to change so much. The Biancos when on sale for 20% off are a very decent buy, but Bambino doesn't do the sales often enough. At regular price, they're too close to the premium products that last nearly twice as long as them. The TotalDry Plus are the most affordable, especially when on sale, but are utter garbage that split down the back half the time, and only last for one light use.
I would really like to see a product of the quality of Biancos for sale year-round without the usual 20% AB/DL premium tacked on. $1.25 for that level of quality would be ideal for me.
