WTB: 80 or 125 bottle/Tank/Cylinder in the Southern Ontario Area

I'd like to go tig and light up some thin stuff and have finally acquired all the necessary accessories except for the argon. Been combing Kijiji, ebay, CL and local classifieds but have come up short. All that's really available are those small 10 CF bottle to fill party balloons. And anything of any use is out of province or would cost the same amount in gas/drive.

Have checked out praxair, canox and airliquide but they are highway robbers. A new tank and fill will net about 250 CAD and only available in 40 CF. Then bring it to them to swap for a used one, wtf! Seems they don't like to sell personal tanks larger than that for some reason. Leasing a tank is even worse and too much for my needs. So I come back to you, the community! Does anybody living within a 2hr drive of Cambridge, ON have a high pressure cylinder they could part with. I'm looking to spend less than 100 CAD, if possible.

If all else fails, I'll have to trade my 40 CF O2 bottle for the argon, affectively nullifying my gas welding setup. REALLY don't want to do that just to get 40CF of argon. (2 - 3 Hrs torch time?)

Have you checked Princess Auto? I hear they are like our Harbor Freight and might have a small bottle at a fair price.

How many tanks are you look for and what pressure 2015 lbs or 2265 lbs and size they make 80cf,110cf and 125cf once you tell me what you want I will ask around for you and do you want them with what gas or none and type of gas?

Already checked at princessauto and they don't sell bottles. At least the ones I go to. TSC has them too buy like the LWS they retail for big bucks. Akin to buying a car, if you want new, it'll cost you.

I only need one tank but would buy 2 if they're cheap enough. Cost is the main issue here. Age doesn't matter much as well as I can get a local praxair to hydro it and be good for a while. If I were to pin it down to what I want it'd be a 125cf S size steel (?) high pressure cylinder with 2015 psig fill pressure and a CGA 580 valve with cover. It'd be filled with straight argon and the 2nd tank would be used for C25, in preparation for a mig setup in the distant future. But I'm not really picky. Anything that'll get me through a weekend Tig welding project would be great. TIA

I will have a price next week on 125CF 2265 PSI tank but it has a CGA540 you will have to get a adapter from CGA540 to CGA580 I use them myself, the CGA540 is easer to find.
