I've been skilletting my boards (fabbed by OSHpark) for the last few months, and it's really easy. As another commenter mentioned, use a syringe to deposit solder paste. It only takes a few boards to dial in the right amount to lay, and is actually surprisingly quick to place the parts (even 0603) with tweezers and then throw 'em on the skillet.
