Out of those two options, definitely Option 2 because it has a continuous horse power motor which basically means it can use it's maximum power at a longer period of time with less risk of burning it out. You should have a minimum of 2 continuous hp if you are running.

I've got a NordicTrack (mid price from Sears awhile ago) and it suits me well. I find that I DO use mine to keep in shape during the winter months because I hate going to the gym. Only on occasion, it's used it as a coat hanger!
