Be careful buying a used bottle. The tank might be expired and need to be recertified. Most N2O stations wont fill an expired bottle. The date is stamped near the valve. More than 5 years and you need to recert. Cost about 50-100, but it takes time. Im impatient!

Also, you need to disassemble the bottle and check the siphon tube alignment and ensure that it matches your setup/alignment. You can change this. Next you want to check what kind of valve is on the bottle. Look at the burst disc/safety valve as well. Wont do you much good if you have a high flow system with a standard valve. Super Flo valves are pricey and generally you can buy a bottle with a blanket and super flo valve filled for around 350. That's a deal when you compare parting a used bottle and superflo valve.
Last, if it comes with an adapter you scored! If not just transfer the adapter when changing bottles.

Good Luck.
