A Studer-Revox linear tracking does pretty good for recording OMR's and HSM's and Nautilus into the computer. Either find one on eBay or wherever that's already been converted, do the quartz lock speed conversion by yourself, or take it in to an audio salon and have them do it.
The other one that works is the Technics turntable I think it's an S-10 or X-10 I forget that comes without a tonearm or a place to put one. It does however come with a place to install an overhead carriage linear tracking tonearm, which you can also get.
Try and find linear tonearms with the optical scanners in. These correct for the varying pitch as the stylus gets to that part of the record by scanning the grooves ahead of the stylus and driving a lead screw onto which the tonearm carriage is affixed. With the scanners, it anticipates where the stylus needs to be when, and speeds up or slows down the tracking motor driving the lead screw right on time, just as a recording lathe pitch control would when originally cutting the master.
IMHO since in the normal two-magnet style of linear tracking, the stylus follows the groove and then an instant later, the magnets line the cartridge back up to the groove portion, the playback always has imaging and other problems. This is because it's tracking corrections are always late, technically leaving the stylus slightly cockeyed most of the time as it's continuously doing it's after-the-fact corrections.
To get rid of the minimal rumble that remains, place a Sorbothane mat onto the turntable under the record in place of its' original slip mat, as well as Sorbothane feet under the turntable itself. Your standard semiconductor Shibata setup or any other good cartridge and stylus should work fine after that.
Or you could just wait for Carl Haber to finish perfecting his disc and cylinder scanner
http://www-cdf.lbl.gov/~av/LBL-RPM-V4-nI.pdf at the Lawrence Berkeley Labs, and then go buy one of his Virtual Turntables once they are perfected. Then you wouldn't have any turnover issues, tracking issues, preamp sound-coloring issues, cartridge or stylus issues, groove-size issues or anything else.
