buying a treadmill

i found the treadmill my gym uses (life fitness hr9500) on craigslist for $1300. the seller is willing to come down to $1100. i think it is a fair price for the quality of the treadmill. they are being sold on ebay for $750-$2300, and refurbished with a warranty for $1995.

if i am going to buy another treadmill, i want a commercial quality treadmill. i have bought and sold two other treadmills for not being solid enough or wide enough. i have $940 in cash but would have to borrow the rest from my hubby. i know i am going to lay down some change for a good treadmill, but i am just not sure that I want to spend that much. i mentally set a cap for myself at $1000.  i think i would be willing to meet in the middle at $1025.

i love this brand of treadmill.  it is easy to use and is reliable.  buying it would save me from going to the gym, but i can go to the gym for 3 years on that amount of money. however, there are many times that i want to run but just don't feel like going to the gym or the gym is closed.

i am very conflicted.  that is a ton of money.  what would you do?
