Exercise machine?

Hmm... Thought of getting an exercise machine to tone my thighs and calves. Can use the capitalmall vouchers to pay some of the amount. I hate my heavy bottoms! Make me look so unproportionate =(

Had done some web search and is considering either of the 2 machines below, one is the stepper and the other is the Leg Magic. Joyce used Leg Magic before, says its not bad and is not din-deh (as in occupy big space). Maybe will go down AIBI one day to test out the machines.
