Funny you mention the cutlass. That's the blade I was looking at, but a bit beefier in the blade. I'll see if I can find it again. It looked more like a drop point Bowie configuration.
I'd be interested to see what you find. While browsing around I also found the Cold Steel Cutlass Machete which is pretty darn good deal for the money, far better than most hardware store machetes.
I do have to echo what others say about getting training time in with any edged weapon. I used to do JMA and now do HEMA. It's also important to have realistic ideas about why an invader would be in the house, what their motivation is, and how they will act when confronted (if you should even confront). It changes the tactics.
