I too have been shopping for drill chucks. Of all places amazon.com sells a Southbend brand chuck (0 - 1/2" and JT33) for $27.00. They sell another HHIP brand that I have that I measure runout by placing indicator on a length of dill rod mounted in the chuck. I get 0.002 swing on the dial. About $30 for the JT33 taper HHIP chuck. The Southbend chuck is still on-order so I don't know about it other then the brand name. Likely the Grizzly is actually HHIP but HHIP makes two lines of chucks that look identical, one they call a "drill chuck" and the other is the "Profesional Grade Drill Chuck" they sell for about $15 and $35 respectively. The pro model is spec'd for < 0.003 TIR mine is about .002 TIR. I'm buying more chucks because I'd tiered of moving mine between drill press, lathe and mill.
What I'm getting at is that the generic Chinese chucks (HHIP is what I consider a generic Chinese brand) can be good if you read the specs and buy the right one. They can also be let's say "suitable only for use in a hand held drill'.. I'm very curious to see if the Southbend chuck lives up to its brand name and still sells for under $30. About hole drilling, Use a "center drill" first. They don't wonder, don't bend and make hole placement literally 10 times more accurate.
