Review of Yamaha Recorder
Easy to clean and performs like advertised
None that I can think of
Review of Yamaha NP11
A "compact & light" touch sensitive digital piano with some nice voices & a budget price.
Could do with a heavier touch & louder power, fussy controls for custom building, naff stand.
Review of Yamaha PSR 340
Compact, portable, very powerful, excellent quality of features and sound, simpler than 540.
No longer made, replaced by E300 and 400 series now.
