68/3k flatline

[jwa158]

is there an older or a newer version of the flatline besides the 4500? i want to buy a flatline from someone i know and i'm not sure if it's an older version if they have one. and if anybody knows it off the top of their head..can you tell me how much they usually go around for used?

I know if theres an "X" in front of the serial number..its 4500. You can look at the manufacturer's hydro label and it will tell you when the bottle was made 09-XXX-99 and what the rating is..i.e. 3500/4500. I would go no more than 150 used...depending on when the hydro date is. They should be re-tested (hydro-static) every 3 years. Take a close look at the bottle itself... if they are any deep scratches or dings/chips etc..I'd say no to getting it. I wouldn't want to speand 150$ on a bottle and it need re-testing in 6 months only to find it fails the test and you can't use it anymore

well, i know for sure it's a 3k, and $150 seems kinda low. i looked in the buying/trading forums and the lowest i've seen is $160, the rest are about 170-190.
