I bought a couple of cheap ones from Tesco last year (Digifusion, or something like that) - were a tad less than £30 each, and they have pretty much been faultless. One reset itself at one point and refusd to come on - quick unplug and leave for 5 mins, plug in and rescan, and 10 mins later it was all good, been fine every since

Picture is FAR better than analogue aerial pictures, and the thing I like most about em is they broadcast a true 16:9 picture - analogue transmissions are sent on "14:9L" format, which is basically just a bit bigger than normal 4:3, and they do this to save on bandwidth for transmission.

Digital TV has far more bandwidth to play with and you get a full 16:9 pic (and I mean full, as in it's filmed like that - yes even the news lol - and not just stretched out) - much better for watching films n the like.

Of course not everything is filmed in 16:9 tho, a lot of American comedy's etc (Simpsons, Friends, that sort of shit) is all 4:3 (for some reason the Americans don't seem to hot on filming TV stuff in widescreen ) so you can only view it in 4:3/14:9L.....
