A controller or a mixer? What's your budget? There are a handful of digital controllers out there with phono line in/out, but I'm not sure on which is better. The S2 is great if you just want a CDJ-like setup, the S4 will afford you more options and can work as a standalone mixer for tables.
This guide might be of some assistance, as they do a review of practically every controller and CDJ ever made, and will give you a good idea on prices and whatnot. The comments at the bottom are also quite helpful.
