My mother is looking to save some money and ditch her Sky subscription (but likes the ease of recording that Sky+ offers). She has asked me what she can do so i've suggested a hard disk recorder. A quick google on the internet and it would seem that the Humax PVR-9300T is an excellent choice (also 5 star rated by What Hi-Fi) so i thought that i'd see her opinion on spending around £160 on this piece of kit. Then i saw the Humax PVR9150T, which as a cheaper option would be better for my mother. Is this an identical box to the 9300T apart from the hard disk capacity, or are there other features which make it inferior to the 9300T ? Thanks in advance for any information.
