That is a very good price but mine is brand spanking new. I do have a used NANO 4500(#10 bottle) that we took off my brothers Camaro after two uses because he lives out of the country and there was no place to refill it. The only place that could get close was the fire department and they could only go up to 25-3000 psi so he may get the 3000psi NANO but I doubt it as he is going TT. The nitrous may stay but it will go down to 50 from a 200 shot.
Any ways, I can throw in the NANO for $1000 and you can get the other stuff. I have a progressive and purge kit but that is for my Silverado truck plus my purge is not the "Big Show" kit but rather the standard one.
