I'm searching for an alternative for Futura Light, I'm going to use it in all-caps display setting, so the lowercase is not important.

The criteria:

-Grotesque, geometric sans
-Quite Light/Thin
-N should have sharp, pointed verticles.
-A should have a pointed top.
-The bowl of P should be relatively large and the curve should be quite round.
-Neutraface has a bit too much flavor and the whole family is too expensive.

I would really want to use something else than Futura for this

http://www.myfonts.com/fonts/quadrat/toronto-subway/regular/ (not light enough)
http://www.myfonts.com/fonts/dsgnhaus/dhsans/light/ (P isn't round enough)
http://www.myfonts.com/fonts/galapagos/contax/contax/ (quite good, not enough. A bit heavy too, "too futura")
http://www.myfonts.com/fonts/ortizlopez/olround-gothic/light/ (too thin, I don't like the A)

Any suggestions?
