I've also used empty SuperJetUSA CISs with success.  See, for example, http://www.superjetusa.com/shop/index.php?main_page=advanced_search_result&search_in_description=1&keyword=empty+cis+1400  --  a page I got to by simply searching "cis empty 1400" on their main page -- http://www.superjetusa.com/shop/

Some allow both types without chaning inks.  See

Beware that (Ultra) Epson Premium Presentation Matte is acidic.  You can buy acid free papers from some companies, like Red River -- 
http://www.redrivercatalog.com/browse/premium-matte-inkjet-papers.html -- for about the same as you'd pay for acidic Epson paper.

For name brand papers, check http://www.atlex.com/ for prices.

There is a lot in information to dig through and lots of different ways to go.
