Reebok I-Run+ (Black)

Ticks all the boxes! Good price £299 at Argos, compact enough when folded to keep in the lounge, so quiet it can be used in the house after the kids have gone to bed - can exercise while catching up on soaps/TV etc. It is pretty heavy so although folding up/down is easy enough, moving the unit from one place to another is a job for at least 2 people. Computer with programs plus manual setting. Heart rate monitor etc. Excellent buy (still can't believe how quiet it is).
