I purchased my Ohaus Triple Balance on E-Bay for $60 + shipping.

I had researched:
HOT BUYS - Balances: http://balances.com/
OHAUS: http://www.ohaus.com/
ACCULAB: http://acculab.com/index.php
EDMUND SCIENTIFICS: http://scientificsonline.com/

All of which brought me back to E-Bay and the reliable, accurate and much less expensive Triple Beam.
