Seeking Advice - Frugal Home Gym vs Gym Membership

I'm renting a home right now and I've got two gym options available.

Gym membership for $300/yr. It includes swimming pools that I may use once a month or so, and a bunch of weight machines I probably won't use. But i will use elliptical, dumbbells, barbells. The cons is it costs $300. 1 min drive or 7 min walk. Will definitely be driving in the winter.

Home gym with weights, and I do my running outside. Conveniently cheap, depending on how many garage sales and Craigslists I can hit up. Cons: I can't run outside during the winter, and the overhead cost of the weights, racks, the floor.

Advice and experiences are appreciated.
