I've had several Nikons, including a F3HP overhauled by Garry's Camera Repair. Under $70 each, some repairs made, seemed like a very through CLA. Quicker than promised turn-around. Will not hesitate to send more work Garry's way.
Also been very happy with KEH Repair. In fact, I have two Yashica's with them right now. Their prices are higher, over $100, but their turnaround time was even quicker. Excellent work, doing more than asked.
