^ Well put
The way I see it is yes there's a write up on how to build a jig to modify them etc. 99% of us already know that. If I can avoid making a trip to the hardware store buying wood to make the jig then busting out my saw to build the jig I rather avoid that. Plus space is also a factor. Hell for $10 just to have that information is well worth it even if you don't win. Most of us blow that in fast food, beer or cigarettes anyways.
