The dealers here are likely the most knowledgeable about these pianos. When I started taking lessons in the early 90s, my parents bought me an M306. All of these pianos were definitely built as ‘entry level’ console pianos with ‘decorator’ cases — so they each have a particular design aesthetic. The 302 and 304 were 42”. When I pick up the 306, I find numbers between 42 and 44”, so it might be a little taller than the other two models. The cases have different furniture styles in all of them. You can Google them to see what they look like.
I think TerminalDegree is correct about the T designating that the pianos were built in Thomaston, GA.
I don’t think Yamaha has made these pianos for quite some time, so my guess is that these pianos are 20-40 years old. I don’t think you should be paying anything close to $5000 for one of these pianos.
Also, if you budget is up to $5000, I would think that there are better pianos at this price point that you could find.
Thanks! Yeah, I've gathered that they are entry level. The three I've found are not quite $5000:
M302 1985 - $3700
M304T 1988 - $4000
M306T 1989 - $3300
I've found some better pianos closer to the $5k mark that I am leaning towards. I don't think the above pianos are bad necessarily, they had a nice, light action, but they lacked low end and resonance compared to the larger models.
On the topic of Yamaha's, what do you think of the M500's? I've also found a few of those. The most promising is a 2004 M500G for $4900.
