Yo big 'Chippie!
I HAVE that Harbor Freight set cause I needed one on a Sunday and they were close. I also have a $60 1/8 - 5/8 one. I use 'em all a lot. I can't tell any difference in how they cut! Buy the cheapies and see if you like 'em. If you don't, no biggie, but if you do get a real good one! I keep one in mt 18V Dewalt all the time.
