I get mine off the kerb on trash day. I find that many people were in the HVAC business as a profession. They retired, and kept a small shop going for a while, but have become old and sick, or died, and their relatives are disposing of their estate. Consequently, HVAC tools and supplies are available on EBay, Craig's list, and other sites at bargain prices. I got a freon recycling rig that sells new for $1700, for $185, and it was in like new condition. Most things i find on the kerb need very little fixing. If they're too bad, i dispose of them and pick up another. Best of luck!!
