I say put your own order in with MAD Amusements. I have used them for 5 yrs n never had one slight issue ever.
**I also respect the opinions of the members who have had a issue, cause blokes like Blair(Pintoxicated) and Pinboligist etc are top blokes n easy to get along with etc so if they have had a issue, then I have to wonder as well, but it cannot hurt to try for yourself and see how u go. If u don't like the service then cancel your order/payment etc.
As for your playfield, strip the entire playfield, clean it well with baby bum wipes, give it a polish n be careful.
Over n above that, use new balls n seek advice from a professional like Tim at Hot Rodded Pins who does playfield restores. I mention him cause he has a proven track record with a spray booth n clearcoating so far and is fully set up n ready for your work so to speak. There are others out there, but get quotes.
I think someone asked a question somewhere about LEDS for this machine. Flat tops in bulk. Don't use 4 or 5 Led LEDS in my opinion, too bright, too expensive.
Buy in BULK from Terry/Pinball Life or Mark in Melbourne, shop around for prices for everything and read everyones terms n conditions.
