JR.com has the AT150 for $250.
You should also check out the Denon DL-160 HOMC. Outstanding performance for the price, usually $150 to $175.

I used and enjoyed the DL-160 for the better part of a year. When I upgraded, I got an AT150MLX. It's true that the DL-160 is a great cartridge for the asking price of $180. It's smooth, detailed for the price, brings out significant frequency extension over any $100 cartridges. Tracks well, tracks reasonably light.
But the AT150MLX is so much better, it makes the $70 difference seem totally insignificant. Add to that that whereas the DL-160 is an MC and therefore has to be replaced when the stylus goes, the AT150MLX has a replaceable stylus for $179.95 (lpgear.com), so once you pay the initial extra $70, the cost of ownership is the same as for a DL-160.
The AT150MLX can elevate your system from advanced entry level to a sense of really digging into what the high end is all about. This cartridge is much faster, more subtle, very neutral, very extended, and transparent over anything you're likely to hear at $200 or below. For all its speed, clarity and accuracy, it is also capable of sounding lush, especially with its way of bringing out the low subtle details such as the way sounds are made by the voice or any instrument, combined with a greater sense of the ambience of the recording venue. It does these things equally well on any kind of music.
My AT150MLX handles chamber music, voice, baroque, bombastic orchestral, rock, jazz, big band, folk, and country equally well. I can't say enough about it, and as much as I liked the DL-160, save yourself the intermediate step, pay the extra $70, and just move into the high end.
Not only is the cart only $250 at J&R, the shipping is free.
