Well, I guess that puts Donny right in there, wouldn't you say? Along with many of our members...
Professional musicians, who, apart from their own instruments, play many other keyboards during the year...
Writing style may suffer a bit here (not many of us care much about that, from what I read

), but at least most of us are not beholden to our advertisers, nor have much editorial oversight. Other than the natural tendency to pump what we actually play, most reviews of other keyboards seem reasonably unbiased, to me.
Add to this that few of the magazine reviewers ever actually PLAY an arranger in their so-called 'professional' part of their careers, to be honest, I'd set more stock in an SZ review than these things. I'll read it for free, but no way I pay £2.50 to read what a WS user thinks about an arranger!
Other than Donny, who never has a bad thing to say about an arranger (that he owns) UNTIL he gets a new one, most of us here are pretty willing to mention possible flaws, wacky OS choices and poor button layout. You'll rarely hear that from a magazine review.
Sorry, but no thanks... (and to be honest, I take it ALL with a grain of salt - OK, a bag-full! - until I play them myself!)
