Ordering coin door + parts

[Helly18]

I have a question about the coin door.
I have the same cabinet as 'toddm' and i would like to order the
coin door from happcontrols so it is fully functional.
What do i need to order (wich parts) ?

1) the coin door that fits in my cabinet (http://www.happcontrols.com/coindoors/40000800.htm)
2) the reject buttons (http://www.happcontrols.com/cc/420517xx.htm)
3) some kind of coin mechanism for euro coins, i think this would work: http://www.happcontrols.com/coindoors/42303900.htm)

Is this about right or do i need something extra like screws, mech. holder
parts, ... ????

Helly, 40-0008-00 comes complete and calibrated for US Quaters.

I don't know about euro coins.

If you want the coin collector that is extra. I just Placed a small baking pan to catch the quaters.

So i guess i have to replace the coin mechs with something like this

Email them and see if you can order it with the Euro coin mech. It may be cheaper this way.

How do you connect the coin mech to a pc? Sorry, I am very new to arcades and want to know the most about this before I start to buy so I don't waste money.
