MorganS:
As you step up to bigger quantities like 100, there are a surprising number of small pick-and-place manufacturers that will do this for you.
Would you have alist of some ?
So far I've been populating and soldering my High Power RGB LED shieled myself ( PID controlled toaster oven)
However I'd be really interested in learning about companies that provide assembly services are reasonable prices. Granted, there are a number of board houses that offer assembly as well but in my experiece the vast majority of these services are aimed at professional users that demand quick turnaround of prototypes. as such the prices are usually rather out of reach for a hobbyist.
