Buttons and Knobs for a G1000???

I am considering going with a glass cockpit for my GA pit build. Long term I want to go analog but until I can put enough pennies in the sim fund jar for that it won't be happening.

For the buttons and knobs around the bezel I want to get as close a look to the real thing as possible so I''ve been hunting for Garmin style hardware without much success.

Does anyone know of a good source for such items?

Still hunting without any luck. If anyone has an idea where to find buttons or knobs with a similar look to the G1000 it would be greatly appreciated.
