Hi
A good Freeview box is hard to come by as most manufacturers have them built into their tv sets and have stopped manufacturing them as a solo box, so there is allot of the brands that people dont want in the shops and many of them are found in supermarkets.
If you want a good Freeview box, i would back 100% the Humax F2-FOX-T which is around £60, it has a What Hi-Fi 5 star rating but the problem is... Humax have discontinued it i think and it is very hard to get a hold of one unless you want a used one on ebay.
If you spend upto the £100, then there is plenty of Freeview PVR recorders out there but its a choice thats upto you.
