i've seen boxes on ebay that say they are 40 or 80 gig for the normal sky+ and then you have the HD boxes that say they are 160-300 gig

but when you look at the wording it doens't say you can actually record for longer periods of time, it just says that they have 300 gig and 160 gig available to store programs on

wtf does this mean then? where is this extra capacity being used?

and for £200 odd quid, might i not just as well pay sky £250 for a box and get a years warranty on it?
