Don't feel bad.
You need the catalogue to really see what they have.
The on-line site is great for specials etc. but searching for specific items without a part number doesn't always work.
Also:
$14 is pretty cheap for a tap that size, I'm guessing you went for the 'KBC' brand which is Chinese.
If you ever need another tap, maybe of a smaller size, go for one made in the USA and relish the difference.
I have Chinese machines because I can't afford the best, and I have American cutters because I can't afford Chinese. They work together well.
