websits for gene exon and intron sequences - (Nov/16/2011 )

Hi, I have problem in finding 5 gene sequences. I need both exon and intron sequences.

I have tried NCBI (it doesn't have introns) and Esemble (the exon sequences are not consistent with NCBI).

Would you please suggest some more websites so that I can try?

Thanks very much! Look forward for your reply!

Cheers,
