I have the small one and have declined the chance to get the bigger one, and
am very happy with it...esp. the small size.  I also have a propex.  The small
one is enough to camp comftorably down into the lower double digits or colder,
but i  insulate my windows (i use alumnium covered buble wrap) and sleep with
the top down when it gets real cold...like below 15-20 degrees.

lots on this in the archives.
