Noise - Jim is correct, a good lathe or Scrollsawing will be quieter than an air conditioner. No problem. Hand carving just as quiet. Do remember to put down a ground cloth for chips though, a lathe throws a lot of curls (I is an old queen bedsheet).
Lathe - I chose the comet for its size, weight, and slow end speed. I'm very happy with it and would recommend it. When I purchased it came with a small nova chuck that works well with this lathe.
The knockdown stand I made takes up little space. I put the lathe, stand, and tormek in the 5er, and the chisels etc (with plastic tubing over ends) in a Stanley water resistant box in truck bed. I built a box that goes on back of 5er for lawn chairs, genny, etc to clear up a little space in the basement.
I also rough turn bowls on the Powermatic at home and just carry the dried blanks, some cut rounds for platters, and a little Watco for finishing.
Traveling now without the lathe, PM me in a few weeks if you want me to send s pic of the stand when I get home. Good luck, you'll be surprised the people that will love watching you turn :)
