Amateur search for extra-solar planets?

Hi all

Are any amateurs seriously looking for extrasolar planets?

And in this case I am talking about using the occultation method where the
planet passes in "front" of the star being observed and the light level drops a
smidgen...

Now, obviously any amateur setup isnt going to be able to detect the tiny drop
youd get with something similiar to when the each "blocks" the sun as seen from
a distance star....not to mention that the distance observer would have to
watch the sun continiously for a year to have a roughly 1 in 200 chance of
detecting earth EVEN is they could measure the tiny drop in light level...

Consider, however, the fair numbers of large, close in, "hot" jupiters
professionals are finding...

Those might be detectable by an amateur setup....a light drop of 1 percent or
so....and the periodicity and duration of the eclipses...and the more favorable
geometries would all help in an amateurs detection efforts..

Is anyone out there trying seriously yet? Has anyone here run the numbers for
scope size, ccd sensitivity requirements, number of stars that need to be
observed etc etc to have a decent chance of detecting something?

take care
