I have this Park chain tool:

and I use it in my home shop. I've had this tool for at least 15 years, and and maybe used it 25 times.
Yes, Park Tools are on the pricey side, especially their professional line. One thing good about Park (in addition to their website and instructional videos) is they sell parts for their tools and accessories, in case a part wears out or breaks. For example, I have one of their lower cost floor pumps (PFP-3, I believe) and have had it for 15 years. The valve head sometimes sticks (won't automatically change between Presta and Shrader)and doesn't seal well at higher pressures. But, for $2.99, I can get a new pump head unit and the pump will be good as new!
