Yes, using the drupal node_import module with the ubercart's uc_product.inc works well.

see: http://drupal.org/project/node_import

uc_product.inc is available somewhere in this forum.

The only issue I found with node_import is that I can't import the images. There is a cck images patch to fix this, but I could not get it to work.... See: http://drupal.org/node/143471
