Quoted from blondetall:Cometpinball.com is Art/Oldpinguy on here and he has great prices on bulk orders. If you are wanting to make your own kits, I recently redid 2 of my machines for about $60 total with his bulbs. I have used PinballLife before and their cheap bulbs are good but not too powerful, so they are best for inserts and not GI. My spiderman came with a Cointaker kit already in it and looks good, but I dont know about paying the high price when I could piece it together myself much cheaper. It just depends on what you are looking for as far as having bulk stock to make your own design or a pre-made kit so you dont have to worry about figuring it out from scratch. Good luck!
Well I've noticed Pinball Bulbs don't charge anymore for a kit than singles... the reason the kit is more $$$ is because of the flipper LED strips, rear PF LED strip and usually 2 dual spotlight setups.
But that's what makes their kits look so unique. Of course you could always get some strips there and then put in your own choice of colors, etc...
