oxy-fuel torch for body work?

Somebody who used to do HVAC work just asked me if I want to buy an old oxy-acetylene rig they have. It's a little Uniweld portable setup with a half dozen burglar bottles. (four of fuel, two of oxygen.) He wants $100 for the whole thing. It is something like this or this
but old enough that the tote is the ugly 1970s shade of green.

I'm considering buying it because the 1930s fenders I'll eventually fabricate will have more complex curves than any body parts I've made so far. That probably means means lots of hammer, shot bag and english wheel, and I've read - but don't know first hand - that oxy welds are much less brittle under that sort of treatment than MIG welds. (I have a buzzbox, too, but I'm obviously not using that for sheet metal.)

Is that a decent price?
Will something that was used for thin HVAC work be able to deal with thicker fender metal?
Is the maleability of MIG and oxy-fuel REALLY that different?

What would you guys do? (Transmaro, PLEASE be one of the guys to offer an opinion here.)

You should be able to get larger tips for the torch if you need them. Be aware that the small bottles will not last a long time. Yes the welds should be more malleable, but that will depend on how you adjust the flame and your skill level. $100 seems like a reasonable price. I still use my torch when I really need to control the heat. I have been restoreing cars for over thirty years.

being that this from HF is $280.... http://www.harborfreight.com/portable-torch-kit-with-oxygen-and-acetylene-tanks-65818.html

only real question is whats the hydrodate on those bottles...

my late grandfather in law has a kit I need to snag one of these times i'm up at the land... has 2 HUGE bottles... but i'm sure they are empty and long out of hydro...

the versatility of a torch is so nice... cut, weld, braze, solder... use it to get rusty bolts out... i'm pretty sure between that and the old stick welder he's got up there he built about everything he ever needed... including the engine hoist I have (a real heap... but it was free and works so I can't justify buying a Chinese made one lol)

A set of cheap torches are usually around $100, not including tanks (though my CDN prices might not be on par with the Yankee dollar).

I recently picked up this DVD on bodywork which certainly toots the horn of Oxy/Acet for bodywork. Dude in the video makes it look so easy. I hate bodywork.

One of my instructors at BCIT widened his TR3 four inches to fit a Nissan drivetrain underneath it. Gas welded the entire thing back together with a 000 tip. Randy Schultz' Triumph TR3 "plus 4"

Teh Googles say that is about $106 US.

OK, that is impressive work >
