Do I really need a dedicated gun or can I adapt something else?

We are a small operation in Al Quoz and only stuff maybe 15 to 20 bags a month, sometimes less. The price of a dedicated inflator feels steep for that kind of volume and I keep wondering if there is a workaround. I have seen people online use all sorts of jury rigged setups and honestly some of them look like accidents waiting to happen. The problem is the nozzle connection seems specific and I do not want to buy some cheap adapter that leaks or pops off under pressure and injures someone. Our safety guy already gave me a look when I mentioned improvising. So I am leaning towards just getting a proper dunnage bag inflator gun and being done with it, but before I spend the money I want to know if the cheap ones are any good or if they all fail quickly. Also do they come with a pressure gauge as standard because that seems important and I do not want to overinflate and burst a bag inside a container. Would appreciate any input from people who do small volume work like us.
