Dont waste ya money on expensive anti ghosting LEDs unless you have to. The ROMS with the ghost patch are very cheap at a few bucks each only compared to a whole machine of the expensive anti ghost LEDS etc.
It only becomes a issue when the patched ROM isnt available to a certain machine but the list is growing that the patched ROMS are available for.
Shop around cause every different seller charges different prices on LEDS. Best to buy in bulk, share a order with a mate or two and get the LEDs much much cheaper. Also, the ghosting is usually only a issue in a very small number of inserts on most machines, and only for a nano second or so. I have done full LED jobs to over a dozen machines so far and its only a very minor issue. You would only have to change over to a very small amount of anti ghost LEDS versus doing the whole machine. hope it helps.
Cointaker premiums or anti ghosting are needed for Stern pins to stop ghosting, can't get a patched rom for them.
