Well dude i am certainly no expert, but i have had a treadmill at home for about 5 years, paid £1200 for it and its always done me fine! No probs at all.
Only thing you have to take into consideration is the size, width and lenghth of the actually running platform part, as i have seen some home treadmills that were too short and too narrow.
I only had a brief look at that one, seems ok! Why not go along to one of there stores and have a butchers! I have been to the northhampton branch, very impressive! All out on display and you can see which model suits you best, if your spending loads of wonga it may be worth the trip.
