IME, the Lenco was the easiest to restore (clean/adjust/lubricate + good idler wheel) to run quietly which is a tribute to its design and engineering. However, it also didn't have the micro/macro dynamics and depth of the G301/401 and TD124. Even if a Rek O Kut (L34/37 or B12GH/H) isn't as refined, it has more of that nice musical drive and energy. A well adjusted stock Lenco reminds me of the virtues of my belt drive Merrill modified/AR + speed stability of my Sony TTS 2500 direct drive. Maybe this is the reason why the Lenco enthusiasts rebuild it from the ground up? PTP chassis, new bearing, etc. but I never went that far.
YMMV, just recounting my experience.
