Digital BW, The Print

Greetings: Excuse the  slight OFF topic question,,,,  I'm looking for 
a place to purchase 100 matts 8"x10" outside dimensions with the 
window at 6"x8"...  Any suggestions??
   To get back on topic I use a 1200 with MIS Vm hex ink with no 
problems,  If I haven't used it for a few days all it takes is a 
cleaning or two and away I go...
  regards Larry
