There's often a Sim Moon handy for sale somewhere, but I haven't heard the piece.. I'd try one for a good price.
I have used and enjoyed a Parks Puffin, and am currently using a Darlington MP-7 and a Pro-Ject Phono Box DS2 USB, in separate systems. Used prices are your friend.
I'd buy something from Darlington Labs or Hagerman Labs if I were strict about the price range and wanted new product and warranty.
