I have to agree, as a WSM owner i love my smoker and i find it great for short smokes (like a 3 hour chicken) to long smokes (like a 10 hour brisket). as for what size smoker do you need: determine the size you need for your family and get the next size up. you think you will need an 18.5 so get the 22.5 WSM. No one ever said i want a smaller smoker, but plenty of people want a bigger one.
As for how much you can fit on a WSM 22.5 you can add quite a bit without cutting. here is a pic of a whole packer brisket (14lbs) on the WSM 22.5
a little room on the side for something small and a whole top rack for whatever you want. it a great smoker, i highly recommend it!
