I don't think you'll regret the CS purchase. I wouldn't be without mine. Finding an HI or a Tora with the same weight and length wouldn't be hard at all. The catch is to watch the specs of the exact khukuri you will buy very closely. The weight and dimensions of Nepali made khukuri can vary widely, even in the same model and length. They're hand made and by different kami. But, even if the weight and length are the same it doesn't mean it'll handle and work the same as the CS Gurkha. You have to look at the spine, taper (or lack of), belly shape and depth, bevel, handle size and shape, balance, etc. "Chopping power" is on you and very dependent on technique. They'll all chop, but some khukuri are designed for chopping and some aren't, same with machetes. A blade heavy beastie (with the right edge geometry) will chop very well. But if light/medium duty chores are your need, then a hand axe may not be what you're looking for. I personally don't worry about getting the maximum power/penetration from each chop. I'd rather put less stress on my arms and shoulders, and 100% avoid the khuk tasing any of my body parts

I would read up on khukuri use and see what technique people use. The HI forum safety sticky should be the first stop. Little things like a wrist flick can do great things to the blade's effectivenes. If you slip that flick into the chop on a sapling and aren't prepared, bad things can happen. I've been surprised a few times when the khuk suddenly became a light saber and was glad I wasn't in its way!
Get the CS Gurkha and play with it. A used one if you can. It'll do everything you want and be a breeze to carry with that great sheath. If you find khukuri to be something you like, then give the traditional version a try. You'll have a better idea at that point what features you'd like to stick with or change, and what you need it to do. Good luck and let us know how it goes.
