I tried renting
compressors a few years back and it flopped because nobody wanted to place a security
deposit. And there was no way that I was going to let about $3500 go out the door with no security
if it didn't come back. One additional problem was that shipping
was a killer so I only had local boaters that actually could afford it.
If you find someone that does it, list them and I will see what their secret is.
