I'm definitely not a piano expert, but I played a couple of Suzuki grands briefly at Costco recently.
I was actually looking at Suzuki grands couple months ago (Costo, yeah, you guessed it.) However, there weren't any on display. I Searched online for any info. and turned up empty handed, so I became suspicious. If you are planning to buy a grand, always test play it, or at least to be able to find some information (other than from the retailer or official Suzuki website.) Personally, I'd never one because it seems like no one has ever bought, or played one. I asked my piano teacher about it, she told me to NEVER buy a Suzuki grand because they are so unpopular (hence, must be low in quality).
