I am looking at the Yamaha 4335G or the Kanstul 700 as my first trumpet (I have been playing cornet for a while ). I can get the Kanstul (used but as new condition) for less than £100 more than the Yamaha, so price isn't the deciding factor. What would serve me best as a mature beginner? Sound-wise I tend to like a somewhat darker timbre, but I realise this can depend as much on mouthpiece as horn; what I am most interested is in ease of playing, quality of built & durability. I don't really want to buy a very cheap entry-level trumpet: I will be sticking with it so would rather have a degree of quality from the start. Thanks.
