Should I buy FTL full price? (I'm cheap)

I'm watching some gameplays of that game FTL: Faster Than Light and looks like a great game. No doubt that I would like that game.

The main question is: Should I buy it full-price (10.00)? I don't think that price is expensive, but with all those indie bundles, steam sales and IGN Primes, I fell like I'll get "ripped-off" to pay full price.

When i was a young grasshopper on Steam, my first 2 games where Braid and Portal 1, both at full price. Few days later a summer sale started and they got 75% off. I didn't regret because I did not know how steam saled worked at that time, but I swore to never buy anything at full price again.

I do have lots of unplayed games that could keep me busy, but I really want to try FTL.

Do you guys think I should break the golden rule and buy it or should I wait some sale/bundle?

EDIT: Thanks for all the feedback. Since my problem wasn't about money, but if I should wait for a sale, I ended up buying it full price at the developer website (10.00), with Steam Key and DRM Free. Thanks again to all!
