I, too, have considered a machete for light brush clearing. Now more than ever really because we are buying a house with nearly two acres of land. I have read lots of good reviews about Tramontina ones. Very inexpensive and apparently very decent. That's probably what I'll buy.
Like this 18" model here:

This Ontario gets good reviews on Amazon and is reasonably priced as well:

Condor makes decent quality stuff - I've considered this one as well:

Kabar Kukri is suppose to be nice though not as long as a traditional machete:

I own a kabar becker bk2, a gerber lmf and a small condor camp knife so I can attest to the quality of these three manufacturers. The bk2 is a great all around knife that I've used many times for yard work. If their kukri and machetes are of similar quality then they should be very solid.
I've have a couple sets of fiskars loppers and they are fine for what they are but I chipped the blade on one of the loppers somehow so that sucks. It's about a pinky fingernail size chip so it oftentimes gets branches caught in it and won't cut through. Kinda sucks. Make me think twice about fiskars.
also - I have this:

and it works great for sharpening my shovel that I keep and edge on, mower blades, and what I'd use to sharpen my machete with if I had one haha.
So while I don't actually own a machete - that's my input for what it's worth. I am a knife guy though and own several decent knives and sharpen my own with a tri-hone or on my lansky system. So I'm somewhat familiar with metal edges
