$100 or less Phono Preamp recommendation?

Hi folks,
Looking for recommendations for a phono preamp that is $100 or less. I'm assuming MM and can be new or used. CD and streaming are my main sources, but I also love to spin vinyl from time to time and have a decent collection of LP's.  

My turntable (don't laugh) is an old Megatech TT-1100 with a Shure cart. I have no idea what cart/stylus, but the front of the stylus says: SHURE HI-TRACK. Anyway, it sounds to me, so that's all that matters, right? :-)) 

Integrated is a Krell KAV-300i and speakers are Vandersteen 2c's. 

Thanks,
JSB
