Resource requests can fit on SE, as long as they're objectively framed.
Does Resource X exist?
Should be fine.
Answering a question like that with "yes" or "no" wouldn't be very helpful, so I suspect what you are actually asking for is a list of those resources.
Read the rest of that answer you linked above. This site is designed to ask very specific questions that can be answered authoritatively and definitively in the space of the post. Asking broadly for a list of resources to pick through later isn't really a great question in the context of this site. Read the section of my answer under potentially dozens of answers, all valid.
Potentially dozens of answers, all valid
The hallmark of a good Q&A site is the best-constructed, "correct" answer rises the top. If the top answer (or the top few) don't complete the issue being asked about, that is neither definitive nor authoritative. Questions soliciting suggestions, recommendations, anecdotes, or polling of the community aren't generally a good fit for this site.
Folks can start answering randomly and something useful might be tossed in the mix, but that defeats the purpose of voting to assure the best, most-correct answer rises to the top.
This comment on your question is asking why anything found in that Amazon search would not work for you. It seems to be guiding you towards a more specific question that can be answered in the space of a post — an answer that is both authoritative and definitive in the context of this site.
That's why the question, as asked, was closed as too broad.
