The big gym question

I decided I need to do more exercise. Now the big question is, whether I shall stock up the (shared) gym of my condo by sponsoring them a weight machine (there is currently none) or whether I shall get a yearly membership at a public gym.

So far, I have checked out the price for a good weight machine for my condo's gym:

How much a yearly gym membership would cost, is still unknown. The gym I plan to go (Fitness First) publishes no membership prices on the web unfortunately.

What do you think how I should decide? Participate the vote...
