I created a virtual appliance install for Drupal 6 with a large assortment of themes and modules; also one with Drupal 7 with a small assortment of themes.
It's real easy to use, and the vmware player is free. If you break your drupal install, you can just extract the zip again and start over.
It's basically a VirtualAppliances.net LAMP appliance with php5-gd, working clean urls, and cron every hour. The Drupal 7 zip has version 6 in /drupal6 but no cron jobs setup.
