If you are in the market for punches check out McMaster-Carr Internet
catalog.  You will need the Adobe Acrobat Reader installed to view the
catalog

Also I found that the Player Piano Co. arch punches are cheaper than any
other place I have found, according to their '94-'95 catalog.  I would
encourage anyone needing punches to purchase them from Player Piano Co.

McMaster-Carr has a greater variety to choose from, with punches ranging
from 3/16" ($7.88) all the way to 4" ($111.51).  They also carry the
oblong punches ranging from 0.5" to 1.5" ($23 - $28).  The small
diameter tube punches they sell range from 5/64" - 1" ($3.64 - $22.96).

Since I did the research and had the info I thought maybe someone would
find it useful.

Have a great day,
