[Jesse & Nicky]

Hi guys/gals -I am bldg away at my k2-100.  I am doing align and test part 2.  I am somewhat slow cause I am handicapped but I am getting there.  My ques is does anyone know where I can obtain scotch type 70 tape ??  I have googled it several times and can only find case lots--not individual rolls.
