Does'nt look complete, says nothing about cutting head or welding torch and not shown in pic. You don't want single gauge like that because it does'nt give tank pressure, never know how much is in tank.
It doesn't include torches by the look and description. That seems like a lot for an old beat up cart and a couple of unknown condition hoses and regulators.

"Tanks can be exchanged at any AirGas/MerriamGraves or local welding supply " That quote tells me the seller probably does not own the tanks.
More often than not, the tanks are not the property of the one possessing them, that to say most of the time the tanks are rented from a welding company and belong to them. I went to a lot of trouble to buy my own tanks (I have the mid size and fill about once a year by my usage). Every time I fill, I have the hassle of having to show my ownership (sales receipts from 15-20 years ago).
Every 5 years, (or 10 depending on the test that was done), the Oxygen tank has to be tested. that is now costing around $30. The gas supply companies are now requiring an inspection (no test) of acetylene tanks every 5 years and the last I paid was about $25.
The month and year of the "hydro" test are stamped into the steel at the neck of the tank and good for 5 years, or month, year and a star for 10 years, if it is even a tank the sell can sell.
From the photo,Looks that they are the best part but I would want a "eye on" inspection before buying.
From the photo, does not look that great, but again, I would want an in person examination.
Are the with the unit, where are they?
Sorry, but it does not look like a good deal to me. I would not do it for half that amount.
No! You may have problems with exchaging the tanks. Check with someone local on this but be sure, many welding shops will not swap tanks that large. Make sure what is included, check a local welding shop for prices.
Maybe it's different down there but around here we just swap tank's as long as we get the same size and the inspection tags are relatively new.
How ever I see no inspection tag on those tanks. You may have a problem.
Also, get flashback arrestors on the regulator and handle.
Burn back: If your oxygen cylinder is low or empty, reverse flow of gas may occur. The fuel gas, being at a higher pressure, can travel up the oxygen line and mix with gas in the hose, regulator and cylinder. If you light your torch without purging the lines, a burn back may occur with explosions in the hose, regulator, or cylinder.
Backfire: The same thing can happen with high oxygen pressure and low fuel gas pressure if a backfire occurs, which is usually caused by holding the cutting torch too close to your work. This causes gas starvation of the cutting flame and results in the flame being sucked into the torch head. Usually you will hear a popping sound that turns to a whistle when this happens.
Flashback: When a backfire takes place in a mixing chamber, unless you shut off the oxygen valve, the flame burning in the torch head may ignite gases in the hoses and result in a flashback. A flashback is an explosion that progresses through the torch, hoses, regulators, and into the cylinders. Consequence can range from a burst hose to a violent explosion of the regulator and cylinders.
