Sad thing is that the hand pump probably would air up my tires faster then that crappy little compressor that I have would.. 
using CO2 to inflate tires -- cheap bastard options?

I am shocked that no one brought up the cheapest and most obvious. Leave the damn air in the tires and forget about it... You know , thats why they make them "Air tight".........

Had one of their steel tanks for two years running. No issues, does the job. Cheap.

Eric, FWIW - my 20-lb setup cost me ~$160, that includes the 20-lb tank (from the swap meet), near-most-expensive high-flow regulator with gauges, 20 ft of 3/8" hose (not the nice'n'shiny coiled deal), and a handful of quick disconnects of all sorts. The swap meet tank lived happily for four years, after which its testing certificate expired - and the welding shop charged me $40 replacement fee and gave me a brand new bottle.
Since then, I've seen the price of a used 20-lb CO2 tank drop to $30.
The only drawback is - a full 20-lb tank weighs 46 lb, quite a heavy mofo. So, if I don't plan on running air tools or seating beads on the trail, I can do away with 5-lb bottle (which I bought new for about $80 or so).
Freezing the regulator - never happened to me in any circumstances, including seating beads and inflating multiple 35x12.5 tires.
Kyle - sure'nuff, but out of my five trucks the only one does not leak air from its tires - that would be the '68 Wag. All others leak. Also, every now and then one may need to undo that trailing arm or diff yoke nut - a handful without the impact gun.
That's great PM.. However, I wanted all the pimp stuff though so I got the Powertank.. Had to impress all the Jeep chicks with my swank tank..
After all isn't that what it's all about

Eric - nothing against the powertank. If I didn't have mine and wanted one, that's what I'd get, saves time. The coolness factor I don't care about - the shiny stuff will get banged up when used.
Kyle - maybe you're right. I keep 40/40 in Michelin XPCs - they already feel kinda hard, on these nice California roads.

there's always the Outback equipped option...

I run the scuba thing in both the Saudi and Lebanese truck...
Costs are:
tank: 80$ used with 5 year certificate
regulator: 40$ used
hose/accessories: 35$ new
fill up (lasts 3-4 trips on 35s and 6-7 trips on 31s): 1.25$ ( )
Really easy to do

Scuba tanks are rated ONLY for "air" though that includes different mixes.
CO2 tanks can contain liquid, which requires different internals to compensate. To compound the mix is it will always contain "800psi" of pressure until it starts to run out of co2 since above that co2 becomes a liquid if I remember correctly. This is why you buy "10lbs" of co2, and "5500 psi/88cubic inch" of air.
Putting c02 in a scuba tank would be stupid as a co2 tank itself is MUCH cheaper (low pressure) and would cause the air systems to freeze up pretty quickly.

so the big question is... which has more volume???
10lbs of liquid C02 @ 800psi
or
88 cubic feet of air @ 3,300 psi (which btw weighs a little less then 10lbs)

Co2 will fill many more tires in our experience.
I ran the PT10 for a long time. There was no way I was losing AC in the last rig...but wheeling at least every weekend started getting expensive and I was always worried about running out... sticking one of these in the RRC
Co2 is the perfect solution for some folks though it just stopped making sense for me...
