.. i am using 4.2.1 and i got very unhappy when i heared that ihave to make the site design from scratch when 4.3 was out. As a previous poster said, x-cart users are medium sized companies and can't afford costs of upgrading. Personally i try to do it all by my self.
And to be true, i am very unhappy for finally choosing x-cart when i has the chance to choose.. Now i am looking the magento and i am crying
