I received my new copy of MSA's catalog on CD yesterday. The main part is a 130MB searchable PDF. It appears to be exactly the same content as the latest printed version, but the prices and availability codes have been updated.

I think that you have to request a copy on their web site, I don't think they'll be mailing them to everyone automatically. It is free, however.

Here's a link to the request part:

Well, the price is right.
