Received from KS just a few days after the auction very fast shipping.
The packing materials were by far the best of the 3 machines I've ordered online. It was packed tightly there was new glass with a protective coating. The machine was completely in tact.
Texas Auction's was fairly well packed but was banged around so much during shipping that the electronics on the back were pulled completely off the pachinko machine, and it did not work immediately. After a few hours of re connecting wires and with the help of their support person it's working.
The only negative thing about Milt is that the pachinko was filthy inside the glass. There is so much dust that it comes off on the tip of your finger.

What is the best way to clean the pachinko machines on the inside from heavy layers of dust?

My experience would put pachinko vendors in this order from best shipping and company to least.

1. Milt
2. Texas Auctions
3. By far the worst bradfishesice who has no support or warranty

Pachinkopros on ebay is one I wonder about?
Their shipping is extreme at 94.99 per pachine their email reply to the cost of shipping was replied with 'LOL'
