I am not sure that Fremer's video would not discourage a neophyte from going anywhere near a record player. Maybe the best advice is to purchase a player with a built-on tonearm (so no installation and alignment necessary) and then ask your dealer to install your cartridge of choice, or a knowledgeable friend. Then, enjoy. If you are smitten, you will take it upon yourself to learn more about the art and science of record playing. If not, you won't.
You will also need a phono stage; the signal that comes out of a phono cartridge is tiny in magnitude (voltage) compared to that which comes from any sort of silver disc player (CD/SACD/DVD), and it needs to be equalized, which is the unique job of the phono stage. Decent ones can be bought for well under $500. (Check out phono stages on Audiogon.) For a cartridge, I recommend any of several good "moving magnet" (aka MM) cartridges. As a class, MM cartridges work best and sound best with those low cost phono stages mentioned above. Shure, Grado, and Ortofon, among many others make good MM cartridges.
