Treadmill options for $1000 (Read 285 times)

I'm looking at buying a treadmill for myself and my wife to use during our Montana winters.  Don't have a ton to lay out, but I know that I'll need to spend at least $1000 to get anything decent.  I run between 30 and 40 mpw and she is 15-20.  What I'm wondering is should I buy a lesser treadmill new (NordicTrack 1500 on sale) or something used.  I found the following used locally:

Spirit XT200 w/ 50 miles on odometer (five-zero, not a typo!)  - $899

Spirit XT375 w/ 750 mileson odometer - $999

Any suggestions on these two Spirits?  Or should I look at ordering online?

Thanks!
