I find the Brattons, Snyders, and Berts online catalogs very hard to search through on my iPad. For example: Bratton’s won’t allow a full part description-it stops accepting a typed line at 3-5 characters; Snyders has way too many options to dig through and isn’t Apple Safari compatible; Bert’s doesn’t recognize “radiator shell” as a product, but I know they have them. All three need a good reworking by a knowledgeable commercial website designer!
