I've been buying products from LMI since the 70's, long before the web was around. 
The selection and quality has always been superior, and the pricing reasonable! There are other places I can go to buy materials, but none that I trust as much...

 * The solvents in cyanoacrylate and those needed to clean up cyanoacrylate and epoxy are destructive to traditional lacquer, varnish and shellac finishes, making these glues poor choices for many applications. Most epoxy loses strength at the temperatures reached in hot parked cars, so it may not be the best choice for highly stressed applications around the bridge and neck. 

** These glues make it impossible to disassemble dovetail neck joints!
