I don't knock Stewmac for the quality of their tools, and if they are the only source for a specialized tool, you just suck it up and buy it. What bothers me in particular is their deceptive sales practices on Amazon. Here's a case in point, somebody mentioned the Z-Files. Looks like a great product, here it is on their website for $108.24. With standard $10.00 shipping fee, thats $118.24 total:

And here's the same tool for sale on Amazon for $123.23 with "free shipping". Really? If it's "free shipping", why is it $4.99 MORE on Amazon? Free shipping my hairy a**.

If you do the same comparison with many Stewmac catalog items on their website, you will find that the price on Amazon is ALWAYS either exactly $10.00 or a few dollars more than it is on their website, so "free shipping" is the most blatant and childishly transparent hogwash imaginable. If you have, as I readily admit, quality tools, why not just be up front about the overpricing?
I bought this fret slot cleaning file from Stewmac, not realizing it is just a Ryoba/Hosco tool with the Stewmac logo burned into it. Price $38.46 + $10.00 shipping = $48.46

And here it is for $31.90 with actual free shipping on Amazon. I got it for $27.00 a couple years ago.

I got the Ryoba/Hosco one in two days, and received it before I returned the Stewmac version, and they are IDENTICAL, clearly made in the same factory, with identical materials, just re-branded depending on who is selling them.
Again, Stewmac has superb quality tools, and some specialized tools you can't find anywhere else, but unless you are Pro Luthier, and don't mind getting soaked a little (or a lot) , it pays to shop around!
