I've heard from a lot of other people as well to start with an 8". I think I'll take everyones advice on that I saw one like the 10" you sent me, but an 8" instead.
Also, for $30 more they have this option which to me sounds like it might be worth it?
It seems like it's cheap enough to do what I want and I still have leftover money to get some accessories with it. Filters and such? I'm not sure of everything that I would need.
