I am putting 20 of my taps on tubing this year and will do the remaining 15+ next year, and I bought the one handed tool from Bascom's. I have only pressed on a handful of fittings so far, but I already see the value in this tool. It took me since last spring to decide on whether or not to buy it, but sure glad I did. Being a very small operation like myself, I figure this tool will last me a lifetime if I take care of it.
