Only things you'd be able to purchase are cable card enabled devices, like tivos, PC tuner cards, etc. But you'd still be paying a leasing fee to Comcast for the Cable Card, usually $2.50 less.
Like John posted, any customer owned device still needs a cable card which has a 7.45 a month charge unless it's your primary box on the account.
Motorola, Scientific Atlanta, Cisco & Pace cable boxes were never sold at retail in the US, so any cable boxes on auction sites can have a questionable source. Canadian sourced cable boxes will not work on US systems.
As mentioned, the only retail cable card devices are Tivo's and one Samsung smart media player. Tivo's have their own monthly or lifetime service fee also, those are available at Best Buy, Wal-Mart and at Tivo.com
The boxes you see on ebay and other sites may have been legit boxes for the original owner, but the owner likely did not have the right to sell it, as the equipment is tied to the seller's account. They are responsible for returning it to Comcast upon disconnecting service. Comcast will not activate a box that was sold on ebay or other sites as they consider it stolen.
Those boxes are probably coming from disgruntled customers, or customers who didn't pay their bill and were charged unreturned equipment fees and are just trying to make up those unreturned equipment fees or make a profit.

And I don't suppose Comcast sells these for a onetime charge......just looking for ways to bring my cable bill down. Comcast finds a way to raise my bill each month. Last month went up $1.00 and this month up another 1.00 plus. Before you know it, it's up $10.00 more.
Will have to find another way to bring it down. Thank you both for responding to my question.
Is it possible to purchase a digital converter box that is compatible or equal to the digital converter box that Comcast provides. If so, can anyone recommend one. Thanks.
