This is a great price for a complete machine with topper and card chute. Most of the ones you'll come across won't have those. Card chutes can be obtained from Marco, but toppers are pretty rare. I paid a ton for a topper for mine.

Cards can be gotten for cheap. Just eBay: "vending baseball cards"

They have to be vending cards with one side that isn't glossy in order for the dispenser to work.

Here's a cheap set as an example:

GLWS!

Someone buy this! Probably the cheapest WPC setup you'll come across. P-ROC can take over a Slugfest for anyone interested, so it can be a cheap learning platform for that.

CPR isn't interested (or they weren't when I asked last year) and PPS claims they have the artwork and will reproduce them some day. Believe me, I checked around when I was trying to find mine.
