Number of ESTs for a particular gene?

Is there a way to find the number of EST clones - not reads - that map to a specific gene.
I’d like to use this as an approximate measure of corresponding mRNA abundance

I think if you follow the read to its page, there should be the clone-id also shown.
But to be fair: why don’t you just use the fpkm which is directly attached to the genes and transcripts?

Sorry how does one get the FPKM value?
