looking through the responses, I don't think anyone actually owns an Easychuck. not surprising. Teknatool came out with their tool-less chuck, the Infinity, about 6 years ago but had to discontinue it because they just couldn't sell them. I was lucky enough to get one 5 years ago and love it. In fact, skipping the long story, I now have three of them and a full complement of jaws #1-7 plus a serrated jaw. Despite having three chucks, I find myself changes jaw's frequently and I absolutely love being able to change them without tools in seconds.
But.... word of caution, if you do bite the bullet, make sure you get a complement of jaws asap. It appears that the Easy Wood jaws are unique to the Easy Chuck. The Nova Infinity I own had an advantage in that ANY Nova chuck is compatible with the Infinity using an adaptor. I bought several adaptors and changed over my old Super Nova jaws to make them work with my Infinity. Even though the Infinity is no longer available, I still swear by it and they will last my lifetime.
