Good value phono preamp for MM cartridge

Take a look at the Gram Slee phono stage offerings. They are very reasonable, and have excellent performance for the money.

I use a Lehmann Black Cube with PWX power supply
upgrade, though I'm using it with a low output
MC cartridge (Denon 103D). I've been very pleased
with its performance, and I read an opinion which
said it works even better with MM cartridges. If
you're patient you can probably find one used
for the $400 range.

How about a great value. You can pick up a sumiko or parasound for peanuts and they sound great.
