Best cartridge under $450? No Grados please

I've been reading up on the Dynavector 10x5, Clearaudio Aurum Beta S Mk II, Shure v15vxMR and the Ortofon OM 20. I need a cartrdige for my new analog playback system and am looking to stay under $400-450. Anyone heard these cartridges or any others that are great deals in the price range? Have 'table and arm that Grado's might hum on, so cannot accept recommendations on them.Thanks
