Best phono cartridge under $350

...Yeah, I know. For 350 bucks you can't expect to compete with the stratospheric but like all things in life there is always the "Best of breed" type of performer in any given price range. The Turntable is a Project Carbon Debut Esprit SB with a carbon arm.   Any thoughts on the subject will be appreciated.

Best regards and Highest Fidelity to all.

Take a look at Grado - some great carts for around $350 and should work nicely with your arm.

They offer stellar perfomance in an affordable package

Nagaoka MP150. when the stylus goes, you can upgrade to a MP200 boron stylus for $130. Very musical.
With your tonearm Denon DL103r must be avoided! People always posting "classic" recommendation without even checking effective mass of the arm. Also it is not a $350 cartridge as you need very expensive SUT to make it even work! And it has conical tip.

You can buy great cartridge even cheaper than your $350 budget if you will look for the Ortofon M20FL Super (nude FineLine stylus). On that picture you see my Garrott P77 next to my old M20FL Super. Search for Ortofon M20FL in Raul’s MM thread here on audiogon, this is a great starter! Last year a friend with the same turntable has bought Stanton 881s mkII (Stereohedron Stylus) and he throwed away his stock M2 Red. My favorite Stanton is SC-100 WOS with sapphire coated cantilever, but it’s pretty rare.

Make sure to find reasonably priced cartridge with advanced stylus profile like FineLine or Stereohedron or Shibata. Don’t buy elliptical or conical. And for your turntable look for MM/MI cartridges. My current Ortofon M20FL Super comes with NOS stylus in the box (never used) and styli are still available online for this model. Let me know if you need it.
+ 1 for @chakster ´s thoughts on the Denon DL 103 R. This cartridge is low compliance and low output, and works best in a heavy arm.
