Mettler PL83-S scale for measuring powder to .02 grain

[Manuel]

Don't see this scale for sale used very often and one is available now on ebay.  Would be a top end scale for a reloader (this is the one I use that I like very much).  Do a search in ebay for Mettler PL83-S or look up on the web for a description.  Note that a 50 gram calibration weight does not come with the scale and must be purchased separate (the standard reloaders weights in 50 gram size are not accurate enough to calibrate this scale).

This is not my item. 

Anyone else using this scale?  Any opinions?
