Let's put it another way. What's more impressive, for about the same price:
"Wow, dude, what's that thing under your n64?"
or, "Da fuck dude, you own an arcade?"
Arcade machines average about $250 if you do your shopping, but you can get them sub-100 many times. Sherriff sales of bars are great for it, but selection sucks. If you want to pick your title, $400 is good for most games. Or spend the $1,000 and build your own mame cab.
Much more impressive to most people than some stupid ass Flintstones cart.
