Quoted from FunkyFreshWalrus:People on Craigslist get very mad for no reason. I just made a reasonable $150 offer on a beat EM game that had almost no backglass paint left. Trashed cabinet, poorly touched up playfield. They were asking $300. The seller responded with such anger Like I asked for their first born. Just a no will do. Was all be email, no real effort wasted.
Just find another machine somewhere and move on.
Relative anonymity brings out the worst in people.
Make a personal connection with potential buyers or sellers by speaking on the phone whenever possible.
You'll have better luck.
