For Even cheaper check out the Mora Craft line ($13ish) and the Mora Companion (non HD version) usually $17-18.
For a good cheap machete $13 I'm liking this one. Comes dull but I got it shaving sharp in 20 minutes

They also have it in an 18" version and a version with a sheath for a bit more.
Edit: comes dull

Check out Tramontina 12" machete.
