Westinghouse WB126-B6-D,

[collecture]

I like the Westinghouse Select-O-Matic models too. The WB-60 is small and the big brother WB-78 is not too big either. Both models can be easily modified to vend cans as well as bottles. Six selections and light-up display make them nice looking machines.
I've bought several for in between $75 - $150 - just make sure the vend motor works!

I'll trade a can stack and shelves for a bottle stack and shelves...

I paid $99 for my WB-102.  It can vend cans and bottles at the same time.  Mine didn't have the can spacers, so I use a piece of PVC to keep the cans forward.  It's a great garage machine.  However, it was a real booger to rewire.  This thing had a TON of wires compared to any other machine I've worked on.
