Looking for a good cartridge...

Grados are good value for the money. You can see some at www.audioadvisor.com The least expensive ones are in the $40-$60 range.

My favorites in this price range are the Ortofon OM-10, for a brighter sound, which can be upgraded to the better Ortofon models for only the cost of the replacement stylus, and the Shure M97xE, which is a bit darker, both at the top of your price range, can be had at www.jacksmusicfactory.com, shipping is ususally included in their prices.
