Ok, so I have an exercise question. I would love, love to get a treadmill. However, I live on the second floor of an apartment building with a very noice-conscious neighbor below. So, my options are either an exercise bike or one of those ellipticals. I don't think the exercise bikes are very loud but does anyone know how noisy the ellipticals are? I tried them a few times when I had a gym membership (once upon a time) but I don't remember the noise level.
