I currently have a Cosmos I and a Star III. Have owned the Nova and I think the ability to adjust the vacuum level manually is a big plus.The auto sensing circuit in the Nova and Cosmos sometimes needs to be adjusted and it is a little more difficult as you have to open up the pump unit.I have had half a dozen Sotas and the Star is my favorite.The difference in sound between this and the Nova will be negligable,and used the tables are worth about the same.The Star is what they have been famous for throughout history.
