I have a 721 around 9 months old for sale.
The Model 721 Features Dual Tuners which enables you to record two programs at the same time, record and watch another program, ff, rewind, etc.
Two USB connections and an expansion port for future upgradeability.
The 120GB Hard Drive allows for approximately 90hrs of recording WITHOUT A MONTHLY FEE!
