one trick is to output the header of the next page immediately -- before 
you send the query to the payment processor. The browser should show 
the "top" of the page, and the user will just wait patiently for the 
page to load.

You can even put a "please wait" message in a <div> and then use JS to 
hide the DIV when the page load completes. 

Purists may argue about this hack I guess. But its been done pretty 
often. And its effective, even if JS is disabled.
