Whitetailhntr.. I got a really good deal on it, but you can find them around. Just make sure you check the DOT date, because the tanks are only good for 15 years. After that you will have to fill it yourself or get another.
I bought two firehouse SCBA 44 cu ft tanks 3 years old for $200 each in excellent condition in 2010 so good through 2022. They get new tanks every 3 years at my local stations. They were filling them for free for me until I got a compressor. Got the adapters from Joe B. as well. The last time I talked to the chief over the three local stations he said they had one for $50 they would give me but it was 5-6 years old. I passed because i really only use one of the two I have now.
