i find that all scales - analog and digital - work best when isolated from the vibrations of the press. i have a separate, sturdy/solid table next to my press bench that the scales sit on. without a doubt, the digitals are faster and quite accurate. all scales must be check weighed before use and it doesn't hurt to check weigh during use. even a $30 frankford digital works worlds better/faster than that dang pita lee safety beam. while i have a 505 beam, it's my digitals - chargemaster 1500, mack 20, frankford - that are used 99.99% of the time, and with stellar results. ymmv.
