Love my LSM Mike....
Built tough enough to withstand a nuclear blast, yet with very high standards of quality applied to all the important criteria. My LSM is an SM-90A with 64mm burr-plates and a 4-Pole motor (1,360 RPM) and nearly identical to this current model... http://tinyurl.com/2gqqlp. The Doser is a work of art constructed from a combination of Cast Alloy and Fibre Reinforced Plastic of some kind. This baby does not leave a single grain of ground coffee behind; it sweeps the sides and bottom of the Doser Base perfectly clean each and every time..... No mods necessary.
Without knowing the model of the unit youre considering its a bit difficult to know for sure but with my particular grinder, because of the one piece cast alloy casing, it is quite noisy by some standards and this may be a deterrent if there is a risk of waking family members at un-Godly early hours. Aside from this though, it is a great, high quality grinder and highly recommended [smiley=thumbsup.gif].
