I bought one today
this one to be specific: http://www.argos.ie/static/Product/p...er/9283718.htm
and I love
it. It's small, it hides away and I could just watch shows while doing it. I thought it was going to be crap but I'm delighted that I got it. The arm things felt great too and I only did them maybe 1/2 of the time. I live too far away from a gym to become a member so until now I had just been exercising by walking/running/stretching but the weather's been really crap lately and running on the spot was hurting my ankles and knees.
Anyway I'd totally recommend one of these bad boys for anyone in a similar position to myself
