    I use a 3-gallon, wide-mouth garden sprayer by Chapin. They're available many places online. I cut the pump out and sealed up the resulting opening with a PVC cap and silicone. I installed a presta valve in the hose (cut short) with a hose clamp to secure it, and I use a bicycle pump with gauge to pressurize it. It holds 49-50 balls. The balls won't flow out the opening, but I can reach my largish hands inside and pull out two balls at a time.

    Just get a Corny keg (ball lock style). They run around $60 shipped online and with a like ~$15 of parts you get a pressurizer that holds 55 balls easily and is strong and safe to use. Parts include tire valve stem and lock connector and hose.

    Kegs have a working pressure of approx 130PSI. I pressurize at 50PSI. Well under its limit.

    Myself, I have been CO2 to re-pressurize as ReBounces does; which requires a CO2 tank and regulator. This increases initial costs.
