Dad needs phono stage recommendation for daughter

So, my daughter wants a turntable and that made my day. We are looking at entry level tables such as the new Uturn Audio tables, and the Pioneer PLX 1000 being the upper $ limit as she is saving up for this herself. We're looking for a separate MM phono stage that will better the stages that can be found built into some tables. The phono stage will be used with her Peachtree iDecco amp. Of course, a plus would be MM/MC, but our budget is under $500. I am completely unfamiliar with phono stages in this market, so any recommendations?
