I have developed a database import script to move products, images and product options from Cube Cart to CS-cart. A few of my clients wanted to make the move but were daunted by the prospect of having to start from scratch. So far with a few edits, all seems to be good. One of the results can be seen at www.signaturediamondgems.com. This was a default installation and an import. The thing I love about this is that when you choose an option, the price is updated in real time.
