If you go with a KM, then choose one you like. They all smoke about the same. Go with what looks nicest to you.
The km mini exotica I linked is taller, and has a better hose for less than the one you linked.
I would reccomend looking at hookahstore.com as they have a huge selection and the biggest discount. 20% off any purchase.
If you want tall, get this stem and pick out a vase.
your looking at a 38"-ish hookah. For $80 with everything.
ps (they have it in red, black, and yellow pears.)
