Mike,
First make sure your vinyl is clean. LPs, require some rituals to be performed. It also greatly depends on your turntable, but most importantly a good high quality stylis/cartridge. Moving Coils (MC) are the best, but a high quality Moving Magnet (MM) is just as good. Be prepared to plop down some cash for a good cartidge. I paid $700.00 just for my cartridge alone, but you can get a decent one for a couple of hundred. Audiophiles have been known to spend tens of thousands on analog equipment. There is much that is lost in digital recordings. To the untrained ear, this may not be noticed. But to those who grew up with quality analog experience, know and can tell the difference. Many recording artists know this to be true as well, and are now once again releasing their recordings on high grade 180 and 200 gram vinyl. I just picked up some new LPs a few weeks ago.
If with a decent turntable and cartridge, and your vinyl has been properly cleaned and you still are getting pops and clicks, or skipping, your LP has been mishandled and mistreated.
All our albums, probably well over 1,000 of them are in mint condition, but that is because we have treated them with kid gloves all our lives, and never played them on an inferior turntable and stylis. If you stylis is worn out replace it before you damage your precious vinyl.
A good place to buy cartridges from is

Here is the cartridge I am using.
The Ortofon 2M Black
Ortofon 2M Black Phono Cartridge: The 2M Black is the new moving magnet flagship from Ortofon.
Edit: One thing to always keep in mind, new cartrdiges have to be properyl aligned, so be sure to use an alignment protractor or gauge and take your time to get it right when mounting it. also make sure your tone arm is adjusted properly. A good quality turntable is well worth the investment for the true audiophile.
