If you want to do careful spot modelling, you would want the 0.001mag range
for the eclipses, so Michael's multi-telescope idea is not far-fetched.
You will have difficulty at this magnitude level, however, if you don't
transform your data and account for second-order color extinction as well.
Certainly a first combined trial wouldn't hurt, then do the fine tuning.
   I'm planning on observing the Sept 17 event for TrES-1, and I'd
be observing the HD209458 event tonight except I've got too much
all-sky calibration work to do!
