YAMAHA CHROMATIC HARMONICA NO.-1200

Hi,

I was given an unused YAMAHA CHROMATIC HARMONICA NO.-1200 recently and was wondering if anyone had an opinion on the model. A google search brings up quite little except they haven't been made for a while (decade or more) and any reviews were vaguely negative.

Being completely new to chromatic I'm wondering if it is worth using or if, despite the freebee, I should invest in a 270 or CX12 to do my learning on.

Thanks for your time.
