By stock, I meant a piece of material that other scrapers can be cut out from. The pieces I have bought are about 1/16" thick, and about 3 X 6".

I don't see any advantage to using anything thicker than this, unless you are making a scraper plane.
Everything at Stewmac seems over-priced to me. Many in the violin making community purchase blue spring steel stock from McMaster-Carr and make their scrapers from that.
If you're primarily doing flat surfaces, you might want to consider these:

I have both the large Veritas Scraper plane and the Lie Nielsen 212; both are fine tools and work excellent.
I bought the large scraper plane for a family heirloom project, a white oak pedestal table that someone scraped all the tabletop surface varnish off at one time. Some of the lamination joins need fixing before I refinish it, and I thought the scraper plane would be ideal for getting the surface ready for refinishing.
