re: Keyless Drill Press Chuck

Room makes decent stuff.  I bought the cheapest thing I could find on Amazon that appears to be a Rohm clone and compared it to a Proper Rohm a friend has on his DP.  The difference were minor and runout was measured about the same, both at <0.0003 in.  The difference between the cheapest and midgrade has severe dimishing returns, 5× the price and maybe 1.5× better.  The name has $$$$$$$ attached to it though.
