EST-insert size

Discrepancy actual EST-insert size and length of the database 

Dear collegues,
I recently posted a message that EST clones obtained from a Resource 
centre did not contain any insert. Somebody suggested to order clones 
from an another centre which worked nice because these clones 
have inserts. But only one from five different ESTs carries an insert of the 
expected size (0.5 kb) wheras the other inserts are larger (around 
one kb).  I regret if the question is stupid, but do the EST people only enter 
the size of the SEQUENCED DNA into the database and ignore the rest 
of the clone. 
If so why do they not give the insert size?
If not should I dump the 1 kb clones or are they worth further 
characterization and sequencing.
