do you want small cell or natural cell? if you go foundationless, you get natural cell. if you want small cell buy small cell. my personal opinion, backed by the article on the research posted by TwT the other day, is that small cell is a waste of money. some people swear by it. do your research before you make up your mind which way to go.
a package is probably the way to go if you want to have them draw their own. a swarm would do nicely, but hard to count on getting one.
