I love me some new HAIR!!

So it's at that point of my life again: I need to decide on my next hairstyle. I have had my natural all summer and it's getting thinner, dry and brittle due to all the changes in the weather; how sad :(.
But the exciting bit is in about 3weeks time I will have a new hairstyle on YAY. I wanted to do a short weave but I have had my hair short all summer so its gonna be a long weave.
Here are a selection of the possible styles:

Over to my lovelies.
Which one do you think is the best? And also ladies, do you know anywhere I can get weaves for great quality and cheap?
Also what brand will you recommend, bear in mind am a student lol.
These days brazilian hair is the new in trend but oh so expensive gosh :(
