Which networks offer XML-Product Data?

Hi there,
just a little question: I am looking for an affiliate network, which allows me to download xml product data of who ever i am affiliated with.

There is one restriction though: it must be an American network or at least there needs to be a decent variety of American affiliates.

I just looked over some at CJ, but it seems like many of their affiliates do not much give a sh** about their product catalogs.

Any Ideas? Thanks in advance!

CJ is ok. They usually give you a choice of what type of feed and normally it is not too hard to convert but I believe XML is one choice. You can ask for weekly updated feeds from up to 5 merchants. Works pretty good for me. Used to use the ATMPRO software from Jeff Johnson to manipulate the feeds for autoblogging.
