Cheap and Yamaha soprano saxophone is a bunch of words that do not compute...
Yamaha only made pro sopranos up to 1998 with the introduction of the 475 series, the going price in NZ for one of these was over NZD4,000.00 (over 2,000 Pommy Squid). I got mine December 2013 for NZD1,500.00 which I thought was a very good price off TradeMe (NZ equivalent of ebay) the bloke I bought it from had purchased a Selmer (Paris) Series 6 (? then later referred to it as a Mark IV), at a guess a Mark VI soprano from the States. My 475 is an early one it has 1700 serial range number has plays very well after my favourite horn repair man, Tim Berger worked his magic...the current 475 Mark II retails for NZD4695.00, here in Kiwiland and the 675 which I believe is to be discontinued is a mindblowing NZD8,000.00 (!?) I would hate to think what the 875 or 82Z sopranos retail for in NZ - I don't think you would get much change out of 10 grand Kiwi dolliros or may be more...
I also have a Walstein soprano (the ancestor of the Bauhaus Walstein current sopranos...) which I have owned for about 7 years recommended by Pete Thomas at the time...
If a 475 soprano is good enough for LA sax man Jeff Driskill - it's good enough for me

until a cheap (!?) purple logo 62 soprano pops along...
Happy sopranoing...
