I am looking for a good 12v air compressor to carry in my vehicle. The only ones I can find in the local stores look like something my 6yoa neighbor would use on his big-wheel. HELP! what's out there in the real world ?

Viair (sp) makes an okay one, it depends on what you are looking to do with it. check the different off-road forums out there or do a google search for "on-board air"

Well, Boghog1 is right, it depends on intended use of the compressor, your car, and your tires. I prefer to keep in my trunk a nonelectric foot pump just for emergencies (like to adjust pressure in the spare tire prior to its installation). Who knows how much juice left in the battery at the time of emergency? Dirt-cheap and rock-reliable:

I'll second the Masterflow, i have two of them. For the price, they are the best deal out there by far. They're selling them at Costco now for just under $50. Just be aware that it needs to connect directly to the battery, not through the cigarette lighter adapter. That's actually a good thing, most of the ones that connect to a cigarette lighter have weak motors, which is why they don't draw enough current to blow the fuses. This one draws a lot more current than those junk air compressors. Make sure your engine is running, cuz I've had it drain my battery enough to need a jumpstart after using it for a while.

Viair and Maxair both reportedly make great stuff, but they have a high price also. I bought one of the Master Flow Tsunami pumps and am more than happy with it. It will even take our RV tires up to 95 psi with no problems...

I'm an avid 4WD person, but I have not been "in the market" for a while now. I currently have an ARB on-board air compressor (the larger one- I understand there is a smaller one on the market now)AND a Quick Air 1 in my rig. Obviously, the primary use for the ARB is to power my air lockers, but I also use it to air up after a trail run. Both of these units combined cannot compare to the ones that could power an air tool such as an impact wrench. However, using both at the same time makes for a faster "air up." I installed an extra 12V socket at the rear of my vehicle to accomodate the Quick Air.
Knowing what I know now, I would first consider what your primary purpose would be. The units that have the ability to power an air tool, to me, would be the best choice because of its versatility- you basically could do anything air related such as popping a tire bead back onto a rim and anything less. The smaller units just don't have he grunt to do that, but you get what you pay for.
If you're looking for an electrical unit, look at the duty cycle. Many compressors have a "time limit" before you have to allow it to cool. Again, that's going to depend on what your primary purpose of the compressor is in the first place.
There are engine powered ones, but that might be over the edge-I understand they're awesome though.

The smaller units just don't have he grunt to do that, but you get what you pay for. There are compressors powerful enough to run air tools without a tank? If you could post a link I'd love to take a look at one of those units. I was always under the impression that you needed at least a 2.5 gallon air tank to power air tools. If powering air tools and re-seating tire beads are a concern for you, it may be cheaper to simply add an air tank to a smaller compressor like the ones in the "quick air" series. Wouldn't be able to run the tool continuously but would be plenty for short bursts and a lot cheaper than a heavy duty compressor.

Air tools need pressure and flow rate, if you can keep both in the right range they work fine.
