I found this old thread and thought I would comment -
I just got a SA5ES tuner from ebay and the build quality is much better than the SA50ES. The SA5ES is much heavier with a bigger transformer. The SA50ES does have some cool features that the SA5ES does not have, like autoprogramming and automatic reordering of the presets.
Sensitivity seems about the same, and is much improved over the ST-S730ES (which would be such a nice tuner if it had better sensitivity).
