The 95gram bottles are about $40+ on amazon (3pack).

Each one last me maybe 6 weeks. My new 5lb is filled and ready.

A 5 pound bottle refill is about $20 at a welding supply or beer supply.

Paintball stores don't cRe about the quality so you will fi d oil on the water.

I recommend the 5lb bottle because it's the smallest most common cylinder.

You can use it to run several tanks and someday you'll get a bigger tank.

Look for used regulators with solenoids.

You could use a 24oz paintball bottle but find out who will fill it in your area.
