Help for first longboard.?

I want to be able to glide over the pavement for a long distance with only a few pushes. I've read up, and apparently I should be looking for a low, drop through deck, with wide, soft-ish wheels. I know nothing about trucks. Anyways, my budget is $200. If you can tell me what is good for what I described(if you even understand), please let me know. I only have ~19 hours before I buy it.
