Jsen,
The DV50(s) units weight comes from the heavy metal (lol) bottom panel (mostly), and middle top panel and some from the two side panels. When one removes the panels and side covers, the unit is actually pretty light after that point. The new DV-60 uses a one peice lighter aluminum top cover and apparently lighter (and thinner) bottom plate. The DV-50(s) feels more like a tank in comparison.
