Well I just received some parts for the machine. I bought all new Happ Competition Arcade Buttons with washers and microswitches from eBay. Upon research on Happs website (
http://www.happcontrols.com/ ) I found these to be the best (
http://www.happcontrols.com/pushbuttons/5896xxl.htm ). On eBay it only cost $1.49 per button/washer/microswitch of any color. Also included in that package was the One and Two Player buttons with the men printed on the button. That came to a total of 14 buttons (6 for each player and the 1&2 player buttons) for $20.86 + $4.05 for shipping = $24.91
I also purchased 2 Happ Super 4 & 8 way joysticks (
http://www.happcontrols.com/joysticks/super_joy.htm ) for $19.99 on eBay as well. Shipping was $6.00 which brought the total to $25.99 for the joysticks. These are the nicest ones Happ offers.
Both the buttons and joysticks were bought on May 21st and I got them on the 24th. That is $50.90 for brand new top-of-the-line parts for this amazing machine. That is a great find with speedy shipping.

Here are the Happ Super Joysticks from eBay.

Here are the buttons, micro switches, and washers that I got off eBay. The button press feels very solid.

Here is a stock photo of the Happ Super Joysticks. Just wanted to show them assembled.
