I'm also inclined to think $150 is too much to spend on a ligature, but it seems that people are piling on the criticism of the Silverstein ligature without having actually tried one out. I'm guessing that a lot of folks speaking out about spending $150 on a ligature wouldn't question enormous expenditures for a Mark VI.
I don't doubt that it might be a good lig. It very well could be, but I don't think any ligature is worth that much.
See, nobody doubts that a different horn or mouthpiece will have an effect on your sound, and you can't deny that a lot of work goes into nice examples of each. But a ligature is a small, simple machine. You can very easily make your own; making your own mouthpiece or sax is more difficult. Moreover, there is debate as to whether or not a ligature can make a difference at all. So even if it
does make a difference (and I do believe so), it's a very slight one. So in that respect, you can't compare the prices of mouthpieces and saxes to ligatures. Granted, there's a lot of hot air in horn and mouthpiece pitches, but I can't help but think that ligature pitches are almost completely hot air. Look at the Ishimori ligatures. Now, I've heard nothing but good things about their products, but let's be honest here: strip away all the talk about material and you just spent $200 on an inverted two-screw ligature. If it were, say, made of nickel and sold by a no-name company, it would cost you under $10. Maybe that fancy circle on it would bring the price up to $25.
That's kind of how I think about the Silverstein. It certainly looks quite pretty, but it's pretty much a few short lengths of cord and a screw for $150. I just can't see that being worth it, IMO.
Of course, I'm not gonna stop you if you want to get one. What you do with your money isn't my business, but I just don't get the appeal of ultra-high end ligatures.
