As Rebecca stated, the C02 tank can be had for much less than $400. I personally run the Motion Offroad one and have been very happy with it.

With the C02 tank you can have it "mobile" as stated above. It's definatly nice if you wheel more than 1 rig (like I do) or if someone on the trail needs air and your not right beside them. It's also nice if you need to take it somewhere (example: took it out of rig to air up bike tires). Only downside I can see is that it does cost to have it filled up, I think I pay less than $10 a tank locally to have it filled.

With the onboard air, your looking at a lot more money to have a nice setup. It takes up a lot more room and is not mobile. Only major benifit I can think of is the fact your air is pritty much endless and only have the upfront cost.

I went with the C02 tank simply for the fact it seemed to have more pro's over the onboard air setup. Not to mention it can be had for a LOT less. Figured it would take me 5+ years of using the C02 tank regularly (like every wheeling event, which I really don't use it) to match the cost of the onboard air.

Just my penny and a half worth...

I just had a thought...

Can you tell us what you are wanting the air for? Anything specific? I guess that might make a difference in some of the advice you get.

Thanks for the input guys!

I guess I didn't realize that the C02 tanks could be had for less than $200. Anyone run the Motion Offroad setup? Are they as good as the high end units?
