I agree with Phillip, and we can already see the first steps towards this in our very own department. The fact that there are so many new mixers using cheaper gear to accomplish basically the same thing others are doing with more expensive setups, shows that the market is already flooding. The next step is to battle on the wage front, this is why it does bother me that someone recording to a laptop or handheld recorder should not be getting the same rate for equipment rental as I would be getting, but they may be.
The camera department is experiencing the same attack with all of these HD cameras flooding their market, cheap easy to purchase and an image that people are happy with.
To respond to Jasony, on most pictures nowadays the "big stars" usually give a gift of some sort. The bigger the star the more expensive the gift, I did a picture with Leonardo DiCaprio and he gave everyone a very nice high end backpack with the name of the show embroidered on it along with "Thanks, L.D." The usual is hats, tee shirts, or jackets from the director and stars and sometimes a gift from production, I have received embroidered CD holders, picture books, travel bags, briefcases. It just varies, you might work with a big star, but for a short time, and they might not send a gift. Only one show, "Rambling Rose" did I have to purchase a jacket for $100.00 each.
