Cartridge help with Rega Planar 3


I have just purchased a used Planar 3 with the RB300 arm. I need to get a cartridge for it and I am considering the budget Rega (Bias-$125) or a Sumiko Blue Point. Any advice is appreciated as well as other cartridges under $150. I don't have experience installing and setting up but it doesn't appear to be to complicated. The rest of my system is a C-J PV10a preamp, Hafler 9500 power amp and Spica TC-60 speakers. Most of my old records are 70's classic rock although I am now into a wide variety, especially enjoying female vocalists like Krall, Cowboy Junkies etc. Thanks for the help.

Thanks everyone for the help. I would still like some comments on the sound of the Bias and Blue Point. I have been told the Blue Point lacks bass. Are Audio Technica or Ortofon still quality brands. As I said, I haven't been into vinyl in 20 years.
Thanks,
Paul
i have an Ortofon OM super 30 (moving magnet) on my RB 300 arm which is very detailed but bright.
about $200. i've heard good things about the goldring, especially the 1042. check out www.originlive.com for great cartridge info for the rb300
