co2 or nitrogen

I'm sorry if this is old news, but I need some advice on airbrushing
my scale models. Which is the better way to go, co2 tanks or no2?
I've seen this discussed in the past, but never paid much attention as
my good ol' Craftsman air compressor did a fine job. It died. Now I
need to replace it, and the thought of all the noise, etc. associated
with the compressor leaves me cold. Any help would be most
appreciated. BTW, I am talking about mostly 1/48 and 1/35 scale
plastic models. I live in the Everett, WA area, it that makes any
Thanks in advance for any help.

IMO - dry breathing air from a dive shop.
If you can't breathe it, it can asphyxiate you...had some personal experience with liquid N2 in an open outdoor environment, so I always recommend against using anything but dry breathable air for one's airbrush.

I agree with Rufus. In this day and age, you can get a really decent compressor with a tank (not a piston machine) for really cheap prices at places like Harbor Freight. I bought one there for under $50, added a moisture trap and it works great. I usually turn it on in the garage, let the tank fill, and then bring it into the area that I have my paint booth. There is usually enough air in the tank to finish whatever job I am painting. That way, you don't have to put up with the noise. I got this one (link below) at Harbor for under 50 bucks. If you sign up for their email ads they will send coupons for $$$ off.

NO2 (Nitrogen Dioxide) is an air pollutant, and poisonous if inhaled. Perhaps you meant plain Nitrogen (N2)

Compressors still offer the cheapest means to pump air through your airbrush. I have a very quiet Paasche compressor with tank, which I added a regulator and moisture trap.
The CO2 tank offers some advantages, but with all the hassles of getting set up and refilling these days stick with the compressor set up.

How about Nitrous Oxide (N2O)? It would certainly make painting the model a unusual experience. "Why does the Hurricane have 'Nazi' airbrushed across its wings?" "It's a traitor! It's Lord Ha-Ha's plane! 'Ha-Ha-Hawker'! Do I have to explain everything?" (Fall on floor while laughing hysterically.)

Yeah, I know its n2, and not no2--since the mind is the third thing to go (I can't remember what the first two are), that's the only excuse I can use!
Thanks for all the good input--the smaller compressor idea seems the best bang for the buck. Thanks again for all the good info.
