It was languishing on ebay for quite some time, so I made a lowball bid and got it for less than $10 incl. shipping. Unlike many of the early RODAC models, these were not serious industrial air tools, but rather an imported line from Taiwan that RODAC rebranded to compete with the cheaper DIYer tool market. T
The chuck is OK but not great, but the real problem is that the vanes in the air motor were sticking. I heated up some Marvel Mystery Oil and poured it in the tool about a 1/4 ounce at a time. After the third pour, it sprung to life and continued to spin freely without hesitation -- a cheap fix.
It's a good enough drill for quick sheetmetal and light duty jobs -- I've always liked RODAC and keep an eye out for the stragglers on ebay.
