Thanks for the feedback.
That is the problem I am trying to figure out right now. I only heard, I never tried. This is the first time for me venturing into the ecommerce field, so I the only thing I can trust at this point are user reviews, and non paid / affiliated articles.
Testing out Presta, Open Cart, Zen Cart, CRE Loaded, and also Magento, as a guy at another forum recommended it as well.
It's pretty tough I tell you, becuase there's no way to predict future problems, and a cart may fulfull the requirements, however it may be a problem down the road. This is why I am trying to gather as much feedback as possible, because I don't want to step into a pile of s**t.
