The Ronstan stay adjusters only advantage I suppose is that there cheaper, about $28 each over here, I recently got given a price for StaMasters $115 each, (but I haven't shopped around either and I can't see how they could be that much). They weigh 65 grams, that would be a around half of the StaMasters (I'm only guessing).
