I am acquainted with Wordpress but have absoultely no clue about the other 2 OpenCart and Prestashop. I have a CSV file ready to import ( with 1000+ products) .
I have already spent last 2 days setting up Woocommerce site, but now I am thinking should I try OpenCart or Prestashop.
Magento I heard is too complex , so probably not for newbies.
Shopify is not free and I am looking at something with low budget.
