Alan, I don't have any specific information. You can google "macklanburg duncan" "smart tool" That should get you there. I think amazon carries them.
I've just gone no mail, I'll be out of town for the next few days, so won't be around. Ciao. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [EMAIL PROTECTED] Tel: (412) 268-9081
