I never liked the Zero myself. Of course, that's because I had to fix 'em. What would usually happen would be that the lubrication in the tonearm would gum up, and it would be hard to get right again, since such small forces are involved. if you're going to worry about the angle of the cartridge to the record, better to use a linear tracking turntable. There were only a few of those I liked, and the ones I did like had 1/2 inch cartridge mounts, and didn't have the tonearm in the lid. I think Toshiba made a nice one. Of course, I can't argue with the "cool" factor. However, good linears are cool too.
