I buy std single LEDs from pinball life in the USA. Cheaper than anyone else last time I checked.
Don't buy super rights cause they are just overkill. Compare to all Aust sellers before u decide on going to USA. I go USA cause bulk ordering has been cheapest. But just dbl check and get quotes n see.
If u buy 100 or more Leds from Pinball-life, he gives u 30 plus percent off.
Buy white and green and red n blue if u really want to achieve some great colours .
Lift ya playfield and count how many 555 or 44 types u will need.
The cost to buy a std kit is a rip off from most places.
You can buy in bulk from a Terry at PL and postage is cheap and even if you buy 100 of each colour or type, what u don't use u keep for next machine or sell to a friend or other member at your cost which will be easy to do. Still works out cheaper than a std already made kit. Ghosting dissapears on Bally Williams machines only csuse of updated anti ghosting Roms.
Buy single std LEDs and u get little to no ghosting. Hope it helps.
I haven't done my Royal Rumble yet, but cool machine.
