Low rise lift hydraulic ideas

So, I bought a low rise lift a couple years ago. The hydraulic pump went out. Looked into options to repair or replace the parts as the lift is pretty sturdy overall. It's not like the quick Jack's, it's very heavy, stationary and meant to be anchored to the concrete. As I've got a nice 9k two post lift in my shop, with plans to put in a second bigger two post in I've been not really doing anything about the low rise. I paid like $500 for the lift, so I don't want to put a bunch of money into it. I would buy a new low rise before I did that. And not working I can't get much for it if I sell it. Does anyone have experience with air powered lift rams? I've seen the rams advertised, I know they have the capacity to lift heavy loads and seem pretty affordable to buy. I have a two stage 80 gallon compressor, so air isn't a problem. I am just curious as to what pros and cons they might have from personal experience. I am not sure what brand the lift frame is, but its burly and does have lock outs, so once it goes up, it's not dependent upon a pressure holding it up. Only to lift to lock outs and to lift to get off the lock outs. My kids keep telling me to scrap it, but I see that as a waste of potential.
