I'm trying to figure out the best solution for my project, which is an online marketplace allowing multiple sellers to sell their (mainly) digital products. I have quite a bit of experience with Drupal so Ubercart with its Ubercart Marketplace module seem like a natural fit. However, there have been no new releases for Marketplace for more than a year, and it's still in beta for Drupal 6 (with D7 already here).

Should I just opt in for Ubercart or are there other good solutions out there?
