Re: O/T harbor freight tools??? quality?
my coworker just bought a 4 1/2" grinder from harbor freight (drill master was the 'brand name'). we used it for the first time on friday and it worked for about 20 minutes before the motor burnt up. just normal use. my ryobi 4" grinder has held up for 2 months and counting of daily heavy use (i'm a commercial carpenter doing a lot of steel doorframes). also, i've had a 12volt ryobi drill for 4 years now and it's served great.
harbor freight grinder: 17.00 lasted 20 minutes.
ryobi grinder: 24.00 has seen approx 45 minutes use daily for 2 months w/o any problems.
for cheap, decent quality, go ryobi (carried at all home depot stores)
