understanding phono cartridges


so as i'm new to the analog game, i dont fully understand what makes a cartridge a good cartridge. and as such, i would like to understand better, so i can make a good decision when i buy the cart for my jvc a-l31. i dont have a whole lot of money to spend, and as it seems the tonearm on this deck is a low mass guy (i make this assumption based on the fact that its a thinner arm) i know heavier carts are out. so im looking at mm cartridges basically. any insight into what really matters in a cartridge, and suggestions that would work for me would be fantastic and greatly appreciated!

The thread referenced above is excellent. You are looking for good tracking, good extension (or "frequency response"), good engineering -- i.e. an old model from a reputable manufacturer...
All that, without being too choosy, should set you back ¬130.
Try a Shure M97xe. They're less than a hundred bucks and they have a very nice warm sound. Not the last word in detail but a very satisfying listen.
actually, the shure was one of the ones i was looking at. its 140 on needledoctor.com, but i know ive seen them cheaper elsewhere
yeah, 60 bucks on ebay brand new...but that will work well on a thinner arm like the one on my jvc?
