My company is an OPW distributor and can buy/sell these units. If you want a functional air tower with a retro look these would be fine, but they are just not the same. I don't think you can put reproduction pieces on it and make it look like an old one, but I could be wrong.
I found a 50's or whatever vintage one and spiffed it up myself to match my pump... it turned out pretty well, was not that difficult and is packed with character!
The above is only my opinion, of course, and if you want a new one I think I can do better than the price you mentioned.
