Need MM phono stage under $300

I am running an Onkyo 806 receiver, B&O Beogram 8000 turntable with MMC20 cartridge, and Polk LSI9 speakers. I intend to get a better amp and use the 806 as a preamp. While the 806 claims to have a phono stage, it leaves a lot to be desired so I am interested in a separate phono stage. The guy that I bought my B&O from raves about the TC 760-LC phono stage and says that I need to spend $1000 or more to get anything better. I had budgeted $300 for this and $700 for the amp. Any advice you guys can give me?
