I have one of those KD sets, too. It's ok, with pactice, you can make good flares with it. It's ok if you're doing wokr on your own stuff. Not really very good for a professional, though. The hydraulic version, like the one I have, is more precise, faster, and will do more than 1 type of flare. It's certainly not an "expesnive gadget". Once I got one, the only time I used the KD was to make a flare demonstration video, otherwise, I only use the hydraulic tool.
