ryan0319:If you Hydro and have them VIPed before you sell them you will get a much better price.
I'd stop at the hydro prior to knowing where the buyer is. If it passes hydro then the VIP is a no brainer ( correct me if I'm wrong). If you need to ship the cylinder to a buyer then out goes the air and with it quite likely the VIP.
I'd price it as a freshly hydro'd cylinder and let the ultimate user get the VIP.
Since it is still a live cylinder I'd try to unload it (them) as is. You are in a very compressed marked (no pun intended) between new cost and what you hope to recover. Any money you pay out may not come back 100%. Best bet may be to make the deal, then execute testing if included.
