I picked up the Boyes set at Tuesday Morning a while back, also. I knew they had had them, so I went digging and found the only set in the store.
As for how I like them... I much prefer the Knitpicks (I don't have the full set, just a couple pairs). The Boyes in the smaller sizes are okay, although the cord is pretty stiff, so no ML. But, when you get into the larger sizes the tips are so short that I have trouble hanging onto them without dropping stitches. For the price you paid, they were probably worth it, since they are serviceable for a lot of things. However in the long run, I know I will eventually wind up buying a Knitpicks set anyway.
