I would never pay $1k for any freaking slider....let alone a 70 or 85 , even if it is a Pepsi "double-dot", my old quote applies here, "Bigger isn't better" generally when it comes to soda machines, ( There are exceptions for extremely rare machines,like say a Vendo De-capper, etc) I swear that crack must be as cheap a chewing gum lately on Ebay.
I've even seen a beat-up Vendo V63 on the Detroit area's Craigs list, with an asking price of $1250.00...yikes!
