Personally I see them as pointless gimmicks, because I would argue that a component can die in six different ways, none of which have any bearing on whether I was wearing an anti-static device or not: 1) Dead on arrival at supplier. 2) Dead on arrival to you via rough mail handling. 3) Killed by the power supply. 4) Killed by people who don't know what they're doing and fiddle inside when the computer is running. 5) Dropped. 6) Old age. I have never known a component to die just because I haven't grounded myself.

Also, do not do the build while standing on carpet. If you walk across carpet, then touch the case prior to touching the components.
Static will take out components, how much is unknown. In my job, I use a static strap OR touch the case while handling the components. This is more a "showing" for my customers than anything. I have yet to know of a component failure because I didn't follow those steps.

To properly use an anti-static wristband, you really also need an anti-static mat. The mat gets grounded to ground and the wristband gets attached to the mat. The computer should be on the mat and all containers should be placed on the mat prior to opening. You should not wear clothing which could touch the devices or computer as it can build up a charge which may not be discharged just because you are grounded and are wearing it.
If you only attach the wrist strap to the computer, then all you are doing is to keep the same charge between you and the computer case, which is better than nothing, but is not the proper way to do it. With that being said, you can get away with not using any anti-static protection and generally you not know what, if any, damage has occurred. I don't always use anti-static protection, but I also know the risk that I am taking and do tend to keep in contact with the case and use the case to set any containers for new devices.

I did a web search and there are many places which carry them, for example a field service kit:
This has the FS kits and lab mats:
