flatline 68/3000 system

[ascent]

Hey everyone, I have a complete AGD flatline system (regulator and tank) that is out of hydro and probably also needs a rebuild on the regulator. also, the gauges are trashed, definitely need to be replaced. I was going to list it for sale on here as I have just ordered a new setup for my old automag classic. Apparently the regulator is desirable?

Point is, I have no idea what to list it for. Help?

I had one and just sold it on ebay for $27 with shipping, so it is worth around $15. I had it listed for sale here and on MCB for $35 and no one ever even asked about it. I think the 4500 psi version if it is in good shape could fetch $50-$100.
