Let me ask you a provocative question. When you build credibility in your field, will you be reviewing papers for free for open access journals?
Paid journals had a point 20 years ago, but not anymore. Most studies are funded by the tax-payers or collaboration with the industries. The authors are not paid. The reviewers are not paid either. Finally the publisher comes along and claims royalty. It doesn't make sense.
And you have to submit your work edited and almost ready to print, it's not like they are doing heavy work there either. I remember one time I submitted an image as SVG but they wanted EPS and asked me to do the conversion. Yes, that oneliner with "convert" was enough.
