i have witnessed the arguement that journals where articles are published without charging any money or those that charge very little amount are of higher standard than those that charge APC. what is your take on this please?
This argument is quite common in some fields of research. Its ground probably is in the perception -- which may be true or not (this is an entirely different issue) but is quite common anyway AFAIK -- that high APCs, save for few well-established exceptions, indicate that the journal in question is not sufficiently selective and is more interested in garnering the APC money from the authors than in careful and unbiased peer review.
The practices of this sort are often closely related to the so-called predatory publishing, see the Wikipedia link below for details on the latter.
There may be elements of truth in your question. I find higher levels of peer review, however more time in journal in which there is no publishing fee. The open access is quicker however there are journals which prey on new researchers in the field. I have been recruited by several of the faster paced to found out still fees as high as $2000 per article were attached to the publication. The key is to find reputable open access journals.
