If the manufacturer uses template pages, you could, in theory, process the web pages and strip out the data to put on your own site. The only problem is that you take a hit in bandwidth, you may run into dupe content issues, and you need to get the permission of the site author before you attempt this. This type of solution would most likely need to be custom made, and get all the permissions in writing first.

I would keep after the manufacturers about creating a feed of their product lines. Especially if the company has multiple distributers such as yourself, such a feed could greatly benefit them, by enabling the distributers to always have up to date product information. Plus, if pricing information or product specs change, those changes would be reflected in the affilated web sites almost immediately, which could be a benefit from a customer relations standpoint for all involved. Imagine the manufacturer finds an error in the power requirements for a product. They fix the error in the feed and within hours every distributer's web site is updated without any extra cost and minimal time involved.
