Hello & welcome to the site! If you could post a picture of the machine that would help, but going from there, Value is in the eye of the beholder (or buyer)
, but depending on its condition, completeness, I've seen these big-boys go between $200-700 , again, depending... in the world of soda machines, bigger isn't better ( unless you find a Vendo decapper laying around somewere!) on the plus side, it's a dry chest (needs no water to cool the soda bottles) which makes it great for the patio party & potato salad. me personally, I'd go as high as $400.00 if the lids were in good shape & it ran/cooled OK, & if it's a straight machine without any rust.
