Can anyone recomend a cheap treadmill?

[Goose]

I suffer from Chronic Fatigue Syndrome so i'm only able to cope with a very light exercise which pretty much means walking and nothing else. The area I live in is not a nice place to go for a walk so i'd like to get a compact folding treadmill (I dont have a lot of space) so I can regiment my exercise precisely. £200 would be my absolute max budget and after looking on Tesco and Argos etc my concern is that they might all be too small. I'm 6 foot 2 and have size 10 feet and i dont want to waste my money on something that wont be unsuitable.

Thanks

With chronic fatigue running is a no-no, it really is only gentle walking that I can do. I've been looking on gumtree and there are a few going for £250 that were £500+ when new so i might take a punt on one of them. Given that I will only be walking on it I dont need a proper fancy and 100% robust treadmill.
