After reading several online reviews (e.g., on http://www.oldjimbo.com) I got a Valiant Trading Co. Large Survival Golok earlier this week:
This golok is the closest thing I've held to a +10 vorpal sword.
Workmanship is very nice. It's nicely balanced and the buffalo horn handle is comfortable. The blade is ~15.5", hand forged, with a full convex grind and distal taper (thins towards the point). Weight is about 1.2 lbs. It came sharp enough to cut limply hanging newspaper. I almost sliced off my finger tip when wiping off the preservative oil it came in!
They're made in Java, then imported into Australia, then shipped to the US. I bought it from their US dealer, but just read on THR that he's closing up shop. Cost was $89 after shipping.
I took it out back today and used it for pruning some arborvitae. It works really well on woody plants, much better than a machete. The blade cross section prevents it from getting stuck the way a machete can. The handle was comfortable in use. The edge stayed sharp and didn't show any damage even after using the golok in lieu of a hatchet to chop down a couple trunks. I can see this golok being very useful in the woods.

Chopping into a branch. You can see how deeply the golok bites:
