Yes, I have to agree. In fact, I use the Gold series from Rio Grande which is their best blades. The O2 size are quite thin and can brake pretty easy, but that size allows you to turn easier and get the fine detail without breaking the material. A good piece of pearl is about $8, if you wreck that because you didn't have a good saw blade, all the cheap saw blades in the world aren't worth it. $8 is like 3 dozen blades. When you're working on a piece like that one below with no etching (I don't etch or paint fretboards), you'll be glad you have the nicer blades. Just my 2 cent, for whatever that's worth, which probably isn't a lot.
