Buying a comic for $1000 CDN

Hey everyone! Recently I was asked a question..."What comic would you buy for $1000 cdn  that would be able to flip in 2 years and make a profit?" My initial reaction was to see what Marvel has on slate for the next  2 years (movie wise) and make your decision. Unfortunately, this doesn't include many, many other comics SO, I ask people like yourselves who know about comics and worth...

What comic would you buy,right now, if you were given $1000 cdn to flip in the netxt 2-5 years?

I'm not Marvel specific so all comments are welcome.
