I spent:
$70 for a 5lb tank filled w/ co2
$25 for a regulator that came w/ a needle valve (from the SnS)
$1 for 10' air tubing
That's the bare minimum you'll need. Maintenance is easy and cheap, I refill my 5lb tank probably every 3-4 months and it costs $12 and takes about 30minutes out of my day.
Side effects are none, only danger to worry about is maybe transporting the tank just make sure you don't hit it so hard the valve breaks turning it into a missile in your vehicle/house.
The goal of co2 in the tank is to dissolve most of it in the water so breathing it isn't a concern.
