I finally got a copy of my grandfather's 1917 birth certificate when I was in Salt Lake a few months ago. I had seen it years ago, but was too cheap to pay for an official copy. I thought it listed his first name along with both his middle names. My memory was incorrect, only one middle name was listed and the anglicized version of his mother's name was used. I also got his time of birth (2:45 a.m.), which I didn't have before. It's always good to get these events down as precisely as possible!
Remember that the Family History Library may have something on film which you sometimes can get much cheaper through your branch library than you can at the courthouse. In the case of this birth certificate from 1917, even with ordering the film on loan, I saved $6. In states where copies of vitals run as high as $20, the savings can be substantial.
And remember---RARELY do you need a birth or death certificate immediately, via fax, overnight mail, etc. If you are ordering the certificate online from anyone BUT the local records office, you are paying too much.
