OK, thanks for the input folks. Sort of confirms what my
initial feeling had been (but I did not have much experience
with them). I'll check out the 3M as well as some of the
other comments here -- I'm getting quite fond of the little
grinder - nice, light, lots of sparks !!

I have found that the 3m disks purchased in bulk will save you money over
the flapper disks. Especially if they are being used by hired help. If you
have 7"or 9" sanders the disks can be purchased and the worn edges can be
trimmed off for use on 4" tools. A tool is available for cutting down
sanding disks for use on smaller tools.

Greetings all -- I have a couple of the 4-1/2 inch grinders (which
I love) and was wondering from a cost point of view which people
preferred - the sanding disc or the flapper discs for cleaning up the
metal/welds and all the other usual stuff you do with those grinders
( and which works better in general ). I was sort of leaning in the
direction of the flapper discs, but was interested in what others
had to say.

Second part of this is where in the US is a good place to
get the discs and which brand seems to give the best "grind for the
buck" as it were ? What have people been happy with? (I hate
those that you spin up and 1/2 the abrasive flys off before you
even start work ;-) )

I was thinking of ordering a bunch and figured this bunch would
have the most experience.

Thanks for the feedback
