Samsung SIR-T351 ATSC (HD) Tuner
Stay clear of this unit and the Samsung Company products!
I purchased this new in a factory sealed box and not reconditioned. Registered the unit with the serial number for the factory warranty online and began using the unit.  In less than thirty days it locked up and would not work properly. I contacted Samsung to arrange to have it shipped back to a service center for the warranty repair.  They would not accept the item for repair because it was last years model and they did not have parts or work on them anymore.  They offered to sell me the latest unit as a replacement.  How many people out there are going to purchase another unit from a company that won't stand behind their previous model.  Very, very poor customer service and product quality.  I will never purchase any other Samsung product again!
