To Buy or Not to Buy Home Treadmill

We are confused whether to buy a treadmill for home...Cost $1200. Its a used commercial grade Precor. Hell, we should buy, is what i think. Please provide clarity. We want to run 5 days a week atleast. I want to run 1000 miles this year. Reason to buy this specific treadmill: This is the treadmill model we are most comfortable with and have been running on this in Spectrum Health Club.
