You should probably read up on the differences between three pole vs four pole tipi's, too. I bought Laubin's book and then wound up buying a Blackfoot style (rather than Sioux) lodge, and it's a different animal as far as set-up is concerned. I like it, it works well, but it did make for one steep learning curve!
I've got a 16' lodge, and use & set it up alone. Cut & prepared all the poles myself, btw. I stay in it with just a dog and a cat, and sometimes a visitor (when I can convince her!), and it's very roomy and comfortable. Easy to heat, plenty of room for me and lots of gear.
(As an aside: I may actually like my Baker tent more than my tipi. Neither are appropriate for my region / time period, and I really love the open setup of the Baker.)
