Braces or not?...

I found something called invisalign today - not too sure whether i save up for it or not.... i mean its only the front of my teeth that need sorting out...

Front - Overbite, I have only 3 teeth at front/bottom. :P

Overbite, and some teeth are back. some are forward, back is fine

 What does everyone think i should do? If you have stumbled across this page! i hope to have some followers soon :)
