Says here that January is one of the biggest months for surveys.  As one of the largest firms, Synovate would probably get you more surveys and product tests.  Product tests are fun ’cause you get full size products to try out – over the years we’ve gotten everything from foods to portable cribs (well, we’re going back on this last one).  Apply and see if you are accepted (their demographic needs change constantly).  Don’t like it, drop out.  I’ve done that with some of the surveys that took too long and only paid a few lousy points upon completion.
