This is a little late in coming, but for the money, you simply will not beat a Sony ST-S730ES. They're relatively common, and usually around only $200 or so, which is an absolute bargain. Do not that this is not a DX machine, but more of an audiophile oriented machine. You won't find it on fmtunerinfo.com because none of us has gotten around to lauding its glories in a decent review yet.
All of the tuners being built currently by companies like Parasound and Rotel are junk. Sony's current SA50ES is also junk. You might also look for a Kenwood KT-3300D. I have one, but your chances of finding one are fairly slim. This tuner is essentially the same circuity as the renouned L-1000T, but missing the ultra narrow bandwidth and remote. Also on the digital short (and available) list are a Denon TU-800, a Luxman T-117 or T-02 (good deal on Agon right now), or Pioneer F-99X or F-90. All of these are available for $300 or less if you keep your eyes open. I left out a whole lot of digital tuners that are great machines, but virtually impossible to find. Magnums, IMHO, are a comparative ripoff on the used market, although they are nice looking machines.
If you're willing to spend about $600 or so, pick up a nice Tandberg 3001. This was an incredibly advanced machine, and is still better than virtually anything else ever made at any price. You'll never look back. I have no idea what your budget is, so pick what suits you best. Very few tuners would warrant spending more than the Tandberg. This is one area where you can get off cheap, and absolutely MUST buy used. No current production tuners are worth owning, save the monstrously expensive MD-108, which a complete and total screw at the price. Hope this helps.
