That first picture is BEFORE I sent it to High End Pins. I threw the brass on, threw the LEDs in, and a couple of tasteful mods (like the spinning propeller, which is REALLY cool). I still wasn't happy with it, so I decided that it had to be perfect.
HEP is a high end restoration service run by Chris Hutchins, who is considered the best of the best (and there are a LOT of incredible restorers on here). He doesn't sell LEDs.
For LED kits, you can go through Cointaker (.com) who will sell you kits. Just tell Melissa you want warm whites for the insert kit, or use the color-matched ones they sell in the kit as is.
If you want to save a few bucks, get a master pack from Art at Comet Pinball (.com) and mix and match yourself.
Both great companies, so you can't go wrong. Incandescent bulbs are dirt cheap and can be bought through Pinball Life or Marco Specialties.
PM me if you have any other questions!
