Thoughts on best budget phono pre-amp under $400?

Check out the new Mobile Fidelity units.

I have the Parks Budgie, and I think it's nice; brand new, it's in your price range. No MC input, but at this price, that's to be expected. There's a link on Spelly's post that gives the specifications, plus they might allow you to take it for a test drive.

I’ve been using two Grado PH-1 phono preamps, upgraded with Vishay Naked Foil 100k resistors. High and Low gain switch available, so can be used for low output MI or some MC too. They are a bit shy in low register, but for $350 used it can be a very good choise. Retail is US was aboyt $500, i think it’s discontinued series. Looks nice in this mahogany wood boxes.

with vishay resistors on top, amazing for MM cartridges:

Picked up a Lehman audio black cube SE used on flee bay for 450 shipped. Consider it a real good value.
