ksam, steingraeber makes a 170 baby grand and before that the model was 168. they're really special instruments. but if their uprights have your attention and continue to hold your attention that's a sign of "something."

... i have a steingraeber 205 and they too are wonderful instruments. and i recently played two of their uprights and they were wonderful.
basically, best practice when picking out a piano is (a) take your time and (b) listen to what your fingers and ears tell you and (c) take your time and avoid quick decisions.
good deals come and go. but over time you'll have a sense of which pianos in a showroom really capture your attention.
all best wishes in the hunt!
