I use the D-40's as well. Over 3 years and 6 cameras I have only had one give any problems, the flash stopped working. It was still under warranty and they shipped me a new camera within 3 days of recieving mine. I have good clear pictures and a lot of them. I hope I don't jinx myself by posting this reply but I have had really good luck with them. I have bought all mine but 1 from sportsmans guide. I couldn't beat $89.00 each.
