I hate going all the way to the gym to use the treadmill so my H suggested we just buy one. I need no bells and whistles, it just has to have an incline and tell me how far I've walked/jogged. If it told us the calories burned that would be a bonus.
What brands should we look at? Is it possible to stay under $500?
I can't remember the brand that I have, but I love it. I'll update when I get home tonight.
Before buying a treadmill, I recommend you check out this article. It will give you a good idea of the specs you should look for, based on how you plan on using the treadmill.
