Recruiters - to ignore or not to ignore

Probably a good problem to have but with my resume out there I get a lot of hits from recruiters. Mostly they are easy to ignore, low pay, travel or in office. But, sometimes one will catch my eye and I find myself preparing for an interview. So far they have fallen flat (no response or job is on hold) but should I just take myself off these job sites and quietly keep my 2 jobs? I have this "what am I missing" feeling all the time. Can anyone else relate? What do you do, ignore or entertain new roles??
